Definitions
- the present invention relates to polymerization curable compositions for the preparation of biodegradable, biocompatible, crosslinked polymers based on polyvinyl alcohol.
- plastics and moldings produced therefrom as implants for the human and animal body, which can serve, for example, as support and building material for tissue (for example bones).
- tissue for example bones
- these materials should have a high affinity for cells, e.g. Osteoblasts, so that they attach to the surface of the molding and can initiate the formation of endogenous bone material around the plastic ren.
- plastic material which dissolves over time, the degradation products of which are absorbed by the body, and at the same time by natural tissue, e.g. Bones, being replaced.
- the polyme- often can only be processed as a melt or a solution, which makes them not only difficult to handle, but also causes high energy and material costs, since considerable amounts of heat are required or solvents must be removed.
- the crosslinking speeds were low and the shape and mechanical stability as well as the elasticity of the polymers were insufficient owing to low crosslinking densities, so that their use as artificial bone material was virtually impossible.
- An improvement in the rate of polymerization of the caproic acid derivatives was achieved by the introduction of acrylate end groups (M. Mizutani, T. Matsuda, Journal of Biomedical Materials Research 62, 395 (2002)), but the remaining disadvantages were not eliminated.
- biocompatible cross-linked protein fibers for medical applications consisting of polymerized derivatives of biopolymers, e.g. Elastin, collagen and gelatin, spun and may optionally contain incorporated living cells.
- biopolymers e.g. Elastin, collagen and gelatin
- these materials are also lacking in stiffness and elasticity, e.g. unsuitable as a bone substitute.
- the inventors have found that the plastics described in WO 2006/108202 have the disadvantage that the degradation products of the polyacrylate-based moldings there, ie acrylates, unfavorably high toxicity, also due to residual monomers, have for cells, so that already attached cells can die or the addition of other cells is hindered as soon as the biological degradation of the plastic in the body begins.
- JP Patent No. 2003-321624 coatings of similar materials which have good adhesion to various surfaces such as plastics, metals, paper, rubber, fibers, etc., biodegradability and affinity for proteins, nucleosides, Nucleotides, nucleic acids, etc., whereby the coatings can be used for their detection.
- divinyl adipate is mentioned as an example of the divinyl ester starting material.
- the coatings are made by dipping objects, such as a film of polylactic acid, into an aqueous solution of the vinyl adipoyl sugar in the presence of an iron (II) sulfate / hydrogen peroxide catalyst system. Applications of such coatings except for the detection of various cell components are not mentioned.
- JP-A-2001-316465 describes the preparation of water-soluble linear polyesters from sugar alcohols and aliphatic dicarboxylic acids or derivatives thereof by enzymatic catalysis with lipase.
- Divinyl adipate and divinyl sebacate are mentioned as possible starting materials, from which - apparently by enzymatic transesterification with elimination of vinyl alcohol - linear polyesters of the respective sugar are produced with adipic acid or sebacic acid.
- L is an optional lipophilic linker.
- carbonates are contained in the side chain.
- the polymer may also be polyvinyl alcohol, so that when the linker L is absent, polyvinyl alcohol-containing polymers can be constructed.
- the linker L when the linker L is absent, polyvinyl alcohol-containing polymers can be constructed.
- all embodiments of WO 93/18070 A1 are completely uncrosslinked, so that exclusively linear polymers are described there which can only have low to moderate mechanical strength, which excludes, for example, use as a bone substitute.
- WO 2003/37944 describes various polyvinyl carboxyl endcapped with fluorinated side chains which are copolymerized together with 3- [tris (trimethylsiloxy) silyl] - propylvinylcarbonat and with N-vinylpyrrolidone to hydrogels which serve as contact lens material. Although the hydrogels thus obtained are crosslinked, biodegradability is not only not mentioned for such copolymers, but is even wholly undesirable in order to be suitable for contact lenses.
- polysiloxanes which are to serve as prepolymers for the production of biomedical devices (especially contact lenses) and may contain carbonate or carbamate groups in the chain.
- these prepolymers correspond to the formula:
- M (* Dü * PS) x * Dii * M
- M is a polymerizable ethylenically unsaturated radical
- Dii is a bivalent radical of a diisocyanate compound
- PS is a bivalent radical of a polysiloxane diol or diamine
- x is at least 2
- * is a divalent group of research mel is -NH-CO-NH-, -NH-COO- or -OCO-NH-.
- the moieties M and PS may contain in the chain carbonate, ureido or urethane or ether groups.
- M may have a terminal vinyl carbonate or vinyl carbamate group.
- hydrophilic carbonate, carbamate or ureido groups An advantage of the presence of hydrophilic carbonate, carbamate or ureido groups is not cleavage but an increase in the compatibility with hydrophilic monomers.
- 2-methacryloyloxyethyl-vinyl carbonate is mentioned.
- the advantage of the plastics obtained from these prepolymers, in addition to high tensile modulus, is their high oxygen permeability, as required for use as contact lenses. Biodegradability is in any case undesirable again.
- WO 2006/71479 and WO 2001/74932 of the same Applicants also describe the preparation or coating of contact lenses, wherein 2-methacryloyloxyethyl vinyl carbonate and N- (carboxyethyl) vinylcarbamate are again disclosed as possible comonomers.
- the aim of the invention was therefore to provide an improved composition for the preparation of biocompatible plastics, which can be used as body implants, in particular as a bone substitute or as dental filling material.
- the invention achieves the above object in a first aspect by providing a polymerization-curable composition for producing biodegradable, biocompatible, crosslinked polymers, preferably those based on polyvinyl alcohol, the composition comprising:
- X is a heteroatom selected from oxygen, sulfur, nitrogen and phosphorus; each n is independently 1 to 1000, preferably 1 to 50, more preferably 1 to 20, even more preferably 1 to 10, especially 1 to 3, wherein at least 20% of n>2; each of R 1 independently of one another is selected from i) hydrogen, unbranched, branched or cyclic, saturated or unsaturated, n-valent hydrocarbon radicals having 1 to 30, preferably 3 to 25, more preferably 4 to 20, in particular 5 to 15, carbon atoms, optionally having one or more heteroatoms selected from oxygen, sulfur, nitrogen and phosphorus within the chain and / or at the chain end and optionally substituted with one or more substituents selected from -OH, -COOH, -CN, -CHO and OO and ii) n-valent residues of biodegradable biocompatible oligomers and polymers selected from polysaccharides, polypeptides, polyamides, polyesters, polycarbonates, polyethers, and fatty acid derivatives;
- ethylenically unsaturated comonomers selected from (meth) acrylic, maleic, fumaric, vinylpyrrolidone and ⁇ -olefin monomers; c) 0 to 10% by weight of one or more polymerization initiators selected from thermal initiators and photoinitiators; and
- novel compositions according to the invention accordingly comprise as main component, apart from any solvent: one or more carboxylic acid vinyl esters of the general formula (I) and / or
- Vinyloxycarbonylphosphorharmen preferably vinyloxycarbonyl derivatives of acids of phosphorus, in particular phosphonates, the general formula (II) and / or - one or more vinyl esters of an acid of Phosphors, preferably one or more vinyl phosphates, of the general formula (III) as polymerizable monomers, which are hereinafter referred to collectively as "vinyl ester".
- the composition is thus based on vinyl ester derivatives, the polymerization thereof forms a polymer chain, which consists partly or preferably predominantly of polyvinyl alcohol.
- polyvinyl alcohol In the course of the biodegradation of the polymer in the body, therefore, polyvinyl alcohol and, at least intermediately, become primarily
- polyvinyl alcohol is a non-toxic polymer that is commonly found in drug formulations and is excreted without damage to the body.
- fatty acids for example, fatty acids, sugar acids or amino acids are formed, and according to the invention, in particular those are used which, as components of the diet, are also widely used. are harmless.
- biopolymers oligomers and polymers (hereinafter referred to collectively as "biopolymers") as component a) ii):
- biological substances or easily degradable plastics are used which are well tolerated and harmless to the organism. This will be discussed in more detail below.
- the decomposition of the polymers in the body involves exclusively acids of the phosphorus, preferably phosphates, which are likewise largely harmless and sometimes even necessary for the synthesis of endogenous substances.
- a plastic can thus be obtained which is stably crosslinked owing to the presence of at least 20 mol% of polyfunctional vinyl ester monomers (since 20% of n> 2), and which is extremely low, if at all Toxicity can easily be used as an implant in the body.
- both hydrogels eg from low monomer content compositions in water
- PEG-o gels ie with polyethylene glycol as Solvent
- rigid, elastic body eg from solvent-free compositions with a high proportion of polyfunctional monomers
- the polymers thus obtained can be used as tissue supports, for example for heart valves, as a base material for shunts and Stents and as adhesives and closures (eg patches) are used for injury or genetic tissue damage.
- such formulations are also suitable for the production of coatings of various substrates, for example for medical devices, but also wherever low toxicity of the monomers and the polymers is desired, for example in food contact.
- the number of vinyl ester moieties in the composition is controlled by appropriate choice of the parameter n. If vinyl esters of high molecular weight biopolymers, eg above 10,000 or even more than 1,000,000 g / mol, are used, depending on the degree of substitution, there may well be up to 1,000 reactive sites, ie vinyl ester groups, on the polymer backbone, for example in the case of starch as a biopolymer. Due to the potentially high for some applications crosslinking density and to increase the rate of dissolution of the polymers in the body but also in the case of biopolymers as the radicals R 1 less reactive sites, ie up to 50, up to 20 or only up to 10 Vinylester phenomenon per monomer molecule prefers. Specifically, when no biopolymers, but rather monomers or short-chain oligomers (eg dimers) are used as R 1 , preferably only up to 10, more preferably only up to 3, vinyl ester groups are present in the monomer molecule.
- R 1 and R 2 may be bonded to each other so as to form ring structures in which X represents a ring atom.
- X represents a ring atom.
- both multiple vinyl ester / heteroatom moieties can be attached to one Rest R 1 be bound and one or more heteroatoms X more than one of the options for R 1 selected substituent R 2 have.
- very short-chain compounds such as divinyl (thio) carbonate or vinyl carbamate and long-chain or highly branched or interrupted by cyclic structures radicals having up to 30 carbon atoms can be used, such short or long / branched radicals are not preferred according to the invention. Due to their relative volatility, very low molecular weight compounds are more difficult to handle and long-chain or highly branched radicals in the body sometimes difficult to break down.
- radicals R 1 having 3 to 25 carbon atoms are more preferable, and those having 4 to 20, particularly 5 to 15, carbon atoms are more preferable in principle, although, as mentioned above, this also depends on the value of n.
- R 2 is a radical selected from the options for R 1 , these are preferably short-chain radicals, for example lower alkyl or -alkoxy radicals, with regard to the mechanical and the polymerization properties.
- Vinyl ester monomers of the formula (I) are thus preferably of vinyl esters of aliphatic carboxylic acids and hydroxycarboxylic acid having 4 to 20 carbon atoms,

- Amylose and glycogen This selection ensures particularly good compatibility of the degradation products of a preparation prepared from the composition according to the invention. polymer as well as ready availability or accessibility of the starting materials for the composition.
- the R 3 are preferably OH, lower alkyl or alkoxy groups or biopoly- or oligomers.
- both radicals R 3 are alkoxy groups, one of which is particularly preferably a further vinyloxy group, so that the monomer is a divinyl ester of the respective acid of the phosphor which serves as crosslinker in the composition according to the invention.
- the vinyl ester monomers of formula (III) in other preferred variants, may be vinyl esters of nucleosides, nucleotides or nucleic acids to provide useful products in the decomposition of the body.
- each of the compositions of the present invention only one vinyl ester monomer of any one of formulas (I) to (III) may be included, but in that case an at least bifunctional monomer, i. a divinyl ester, in order to give the required degree of crosslinking in the polymerization. Therefore, several different vinyl ester monomers are preferably contained in the compositions, for example at least one mono- and at least one di- or higher-functional monomer, since this makes it easier to control the degree of crosslinking. In the presence of several different vinyl ester monomers, these may all correspond to only one or different of the formulas (I) to (III). That is, for example, combinations of vinyl carboxylates, carbonates or carbamates and phosphates may be included in the compositions. The choice of such combinations is not particularly limited and may be freely selected depending on the purpose of use of the polymer to be produced therefrom, as long as the desired properties of the cured product are achieved in the polymerization.
- the at least one vinyl ester monomer makes at least 50, more preferably at least 70, especially at least 90, mole%. of all the monomers contained in order to give the polymerization of a plastic containing high levels of polyvinyl alcohol, which brings the advantages of the invention described above even better advantage.
- At least 35, more preferably at least 50, mole percent of the vinyl ester monomers of the composition of the present invention are di- or higher functional crosslinking monomers with n> 2, providing both low and high total monomer content the composition - the advantage of a sufficient crosslinking density, dimensional stability and desired mechanical properties, such as Hardness and stability, to ensure.
- heteroatoms can be present in the chain or at the end of the chain.
- sugar (acid) -, amino acid or peptide or fatty acid residues from where the vinyl ester monomers of the invention can be prepared, heteroatoms are frequently encountered.

- the optional comonomers as components b) can be included for a variety of purposes, such as for surface modification to promote cell attachment, for fixed attachment of certain components of the composition, such as initiators or optional additives, for example for fixation at certain points in the Molecule, but also for modifying the mechanical properties of the polymerized product.
- certain components of the composition such as initiators or optional additives, for example for fixation at certain points in the Molecule, but also for modifying the mechanical properties of the polymerized product.
- biocompatible, non-toxic compounds are also preferred for this purpose, but other substances, such as, for example, acrylic and methacrylic acid derivatives, may also be used in small proportions. This also depends on the other components of the composition and on how and at which positions these comonomers in the polymer chain should be installed.
- the comonomers are preferably used as component b) of (meth) acrylic anhydride, glycidyl (meth) acrylate, (meth) acryloyloxy succinic anhydride, (meth) acryloyloxymethyl succinic anhydride, (meth) acrylic acid 2-oxo-1,3-dioxolanylmethyl ester, vinyl succinic anhydride, Vinylene carbonate and maleic anhydride, since these derivatives are relatively well tolerated and / or can easily enter into compounds with desired partners, such as functionalities on cell surfaces, additives or initiators.
- ring opening radically polymerizable comonomers such as cyclic carbonates, which interrupt the polyvinyl alcohol backbone and can be cleaved in the body, so as to provide shorter polyvinyl alcohol chains whose clearance is easier and faster.
- At least one of the monomers or comonomers has functionalities capable of being promoted via major or minor valences, e.g. Van der Waals forces or hydrogen bonds to bind to cell surfaces or receptors.
- functionalities capable of being promoted via major or minor valences, e.g. Van der Waals forces or hydrogen bonds to bind to cell surfaces or receptors.
- this ensures good cell attachment to the cured polymer, but on the other hand, living cells can also be incorporated into the composition as "additives" in a known manner and immobilized via these functionalities.
- Polymerization initiators may be included in the composition, for example, when it is a UV / VIS curable composition. However, the polymerization can also be triggered thermally or by electron or gamma radiation without an initiator, which is not preferred. In preferred embodiments of the invention, 0.1 to 10, preferably 0.2 to 5, more preferably 0.5 to 3, wt .-% of at least one polymerization initiator as component c) are included, since the curing thereby cheaper and more complete can be carried out.

- the composition may contain a solvent, such as when the desired product is a hydrogel.
- a solventless composition is preferred, for example, for use of the composition in rapid prototyping or rapid manufacturing processes.

- fillers include tricalcium phosphate, Ca 3 (PO 4 ) 2, and hydroxyapatite, which on the one hand serve as a calcium source for bone formation, but on the other hand also improve cell adhesion, as well as a wide variety of organic fillers, including, for example, autologous serum or plasma of the transplant recipient ,
- One or more additives may also be covalently bonded to monomers or comonomers, e.g. to one or more of the above easily derivatizable comonomers as discussed above, such as esters or other functionalities of the (co) monomers.
- This can not only ensure a more uniform distribution of the additive than it would possibly be achievable merely by physical mixing with the other components of the composition but, for example, also a binding of a specific component exclusively to the surface of the polymer, if the corresponding additive is added first, after a pre-hardening of the other components has already taken place. Therefore, it is particularly preferred that at least one such additive covalently bound to monomers or comonomers be a bioactive agent such as e.g. a drug or agent for promoting cell adhesion, since such an agent has to fulfill its function predominantly on the surface of the finished plastic.

- the present invention relates to a process for producing such a biodegradable, biocompatible, crosslinked polymer by polymerizing a composition according to the first aspect of the invention.
- a portion of the composition may be precured, after which the remainder of the composition is added and the mixture is cured. This allows the targeted binding of some components of the composition on the surface.
- the polymer thus obtained for example, for postcuring, removal or deactivation of excess additives or residual (co) monomers or for modifying the surface or the mechanical properties, but also for sterilization for its use as a graft, aftertreated.
- Post-treatments may also include heat treatment, extraction, reprecipitation or surface treatment, e.g. impregnation, include.
- the polymerization can be initiated thermally or photochemically.

- the solubility of the starting polymer is usually significantly improved by the conversion into the corresponding vinyl esters, but solids are obtained virtually throughout.
- liquid comonomers and / or solvents in more or less high proportions are required.
- 5% (for example 1%) solutions of the monomers in the respective solvent are also possible, they are not preferred according to the invention, since these give slow polymerization rates and usually require a high expenditure of energy for the subsequent removal of the solvent. Shaping in rapid prototyping would also be difficult.

- ALP alkaline phosphatase
- a polymer flakes with 1, 3 cm in diameter was inserted and in 0.05 M Tris-HCl buffer at pH 8 and 0 4 shaken (2 mg / ml) for C 16 h in 3 ml of ALP solution.
- the plate was washed several times with the buffer solution, and free, unreacted carbonate MC was reacted with ethanolamine.
- Comparative Examples 1 to 8 Preparation of Reference Compositions Analogously to the above examples, instead of the vinyl ester monomers according to the invention, other photopolymerizable monomers were mixed with initiator in order to obtain the reference compositions V1 to V8, which represent the prior art as comparative examples.
- Comparative Example 3 ethoxylated TTA, MW 1200, ETA initiator A
- Comparative Example 4 polyethylene glycol diacrylate, MW 800, PEG-DA initiator A

- For phtoto-DSC measurements approximately 5 mg of each were accurately weighed into an aluminum DSC dish and the dish placed on the right sensor of the measuring cell, which was purged with nitrogen for 5 min.
- a small bowl with an already polymerized sample of the respective composition on the left sensor served as reference.
- the recording of the DSC device was started 2.0 minutes after the bowl was put on, and after the lapse of 1.0 minutes, the irradiation was started.
- compositions of the examples in which difunctional monomers of the formula (I) were used generally cure with good to very good polymerization rates R p .
- most of the monofunctional monomers cured slower, but are still in the range of difunctional and trifunctional comparative examples.
- t max are in the inventive compositions, although large-part higher than that of most of the Comparative Examples (except for V5, a methacrylate wherein said functional group is generally preferred over the acrylates in practice), but are in a practical for implementation
- the invention quite acceptable range, especially since in preferred compositions of the invention anyway at least 35%, more preferably at least 50%, di- or polyfunctional and thus rapidly curing vinyl esters are used as crosslinking agents.
- Examples 40, 47 and 25 show the best performance of the invention. According to compositions and are in the range of the fastest-starting mixtures of the comparative examples.
- the double bond conversions DBC of all the compositions tested are in the range of those of the comparative examples, with the phosphonic acid derivative of Example 41 giving the best value. It is also noticeable that the two difunctional vinyl phosphates of Examples 48 and 49 also give very high DBC values, but the trifunctional phosphate ester from Example 50 also performs better than average.
- the compositions of the invention thus tested are quite suitable for the preparation of commercial products in an economical manner.
- osteoblast-like cells MC3T3-E1 (source ATCC CRL-2596) were used.
- the adherent cells were first detached with pronase from each other and from the bottom of the Petri dishes and then with freshly prepared nutrient medium, consisting of commercially available Minimal Essential Medium Eagle's alpha Modification ( ⁇ MEM), with additional glucose of originally 1 g / l on a glucose Concentration of 4.5 g / l and with 10% FCS (fetal calf serum), 30 ⁇ g / ml gentamycin (broad spectrum antibiotic), L-glutamine (400 mg / l) and ascorbic acid (50 mg / l), to a cell concentration of 40,000 cells / ml.
- ⁇ MEM Minimal Essential Medium Eagle's alpha Modification
- novel compound N-acryloyl-N-methoxyvinylcarbamate which is a valuable monomer for many applications due to its polymerization properties, is therefore of limited use in the inventive compositions according to claim 1 insofar as care must be taken that no residual monomers contained in the finished polymer product. This can be done for example by means of a post-treatment, for example extraction, reprecipitation or the like, of the polymer.
- human venous umbilical endothelial cells (HUVEC) were used. After trypsinization of the confluent primary cultures, the cells were suspended in commercial medium 199 with 20% fetal calf serum, seeded in 96-well cell culture plates at a concentration of 40,000 cells / cm 2 and cultured again to confluency (37 ° C., 5% CO 2 ). Subsequently, the cell supernatants were lifted off and the endothelial cells were cultured with increasing concentrations of the monomers (0.1 nM to 1 mM in medium 199 with 10% fetal calf serum) for 24 h.
- monomers 0.1 nM to 1 mM in medium 199 with 10% fetal calf serum

- human venous umbilical cord endothelial cells were used again. After trypsinization of the confluent primary cultures, the cells were suspended in medium 199 with 20% fetal calf serum (FCS) and seeded onto the test specimens to be tested (40,000 cells / cm 2 ). After 24 hours of culturing of the cells (37 0 C, 5% CO2) were lifted off the cell supernatants, the endothelial cells with phosphate buffered saline (PBS) and incubated with medium 199 containing 10% FCS for 1 h equilibrated long. The cell proliferation was then determined by means of the EZ4U test.
