Description
REACTIVE MONOMERS AND THE
ADHESIVES AND POLYMERS THEREOF
This invention relates to reactive monomers containing 2cyanopenta-2,4-dienoate and methacrylic or acrylic double bonds in their molecules and the adhesives and polymers thereof.
Esters of the 2-cyanopenta-2,4-dienoic acid have been reported in the patent literature. The ethyl (US 3,316,227), alkenyl and alkoxyalkyl (US 3,554,990) esters have been particularly described. These monomers can polymerize under the influence of weak alkali and are suitable for adhesives. Their use as modifiers to cyanoacrylate adhesives (US 4,425,471) and for the manufacture of photoresists (EP 0404 446 A2) has also been reported.
The present invention provides reactive monomers containing 2-cyanopenta-2,4-dienoic and methacrylic or acrylic double bonds, the polymers and adhesives thereof. The monomers of @@e present invention @@@@ @@ @@@@@@@@
where R@ is H or CH3, R, is alkyl, alkenyl, alkynyl, alkoxyalkyl, poly(oxyalkyl), aryl, cyloalkyi or an aromatic heterocyclic radical. R2 may also be one of the foregoing mo@eties substituted with one or more other of the moieties; this includes the case of a substituent itseif being substituted. Group R2 may contain other compatible constituents, for example alkoxy, alkoxyalkoxy, carbalkoxyalkyl or halogen. In general, R2 can be any moiety which does not contain a sufficiently nucleophilic group to initiate polymerization or sufficiently electrophilic group to interfere with polymerization. The alkyl or alkenyl moiety may be cyclic and normally R2 contains from 1 to 16 carbon atoms and often is a 1C, 2C, 3C, 4C, 5C, 6C, 7 or 8C group, more usually it is a 1C-6C group. In the case of moieties containing a heterocycle, heteroatom ring members are normally counted as a carbon atom.
More preferably, R2 is alkyl, alkoxyalkyl, poly(oxyalkyl), halogenated alkyl, alkenyl, alkynyl, phenyl, halogenated phenyl, phenyalkyl, alkoxyalkyl, alkoxyalkoxyalkyl, carbalkoxyalkyl or alkylideneglyceryl, wherein the terms "alkyl" and "alkenyl" include the corresponding cyclic radicals.
Specific examples of R2 are - CH2CH2 - ; - CH2CH2CH2
- CH2 CH2OCH2CH2OCH2 CH2OCH2CH2OCH2 CH2 OCH2 CH2 and
The reactive monomers of this invention are obtained by reacting acrolein with CNCH2COOR20COCR.I = CH2 where R@ and R2 are the same radicals as described above.
The methacrylated or acrylated cyanoacetates are in turn produced by reacting cyanoacetic acid with hydroxylterminated methacrylate or acrylate monomer or by transesterifying methyl or ethyl cyanoacetate with hydroxylterminated methacrylate or acrylate monomer. A preceding UK patent application by the same authors (UK Pat
Application No ......) describes the synthesis and properties of these methacrylated and acrylated cyanoacetates and could be followed to obtain the raw materials. The reaction of acrolein with methacrylated or acrylated cyanoacetates is chemically consistent in nature to the reaction of acrolein with active methylene compound as described in US 3,316,227. All of the considerations derived in this reference hold true for the present reaction between acrolein and methacrylated or acrylated cyanoacetates.
A distinctive feature of the present reaction however, is the reactivity of the active methylene compound which in the present case contains polymerizable methacrylic or acrylic bonds. Thus in order to avoid polymerization during the reaction it is advisble to use phenolic-type inhibitors, like hydroquinone and p-methoxyphenol, in conjunction with air sparge of the reaction mixture.
If desired mixtures of two or more of the monomers of the invention with themselves or other monomers or polymers could be used.
Usually the reactive monomers of the present invention are stabilized with anionic and free-radical polymerization inhibitors. Anionic polymerization inhibitors could be soluble acidic gases (for example sulfur dioxide), hydrogen fluoride, phosphonic, carboxylic and organic sulfonic acids, sultones, BF2 and its complexes and phosphazenes, for example. The free-radical polymerization inhibitors are usually hydroquinone, p-methoxyphenol or t-butyl catechol, for example.
The inhibitors are normally used in small amounts of from 0.00001 to 1% by weight of the monomer. The preferred quantities for the above-mentioned inhibitors are: acidic gases - from 0.0001% to 0.06%; acids - from 0.0001% to 00l%; sultones - from 0.01% to 0.1%; BF3 - from 0.0001 to 0.01; phosphazenes - from 0.00001t to 0.001%; free-radical inhibitors - from 0.0018 to 1%. The foregoing percentages are percentages by weight of the reactive monomer. It should be noted that the quantity of inhibitor will influence the onset of polymerization of the monomers of the present invention and could be used as a means to control the set time.
The reactive monomers of the present invention may contain polymerization initiators. They could be anionic polymerization initiators like pyridine, aminopyridine, vinylpyridine, methoxyethylpyridine, piperidine, picoline, lutidine, N,N-dimethyl-p-toluidine, N-N-dimethyl-otoluidine, N,N-dimethyl-m-toluidine, triphenylphosphine, triethylphosphine, tribenzylamine, triethylamine, benzyldimethylamine, diethyienetriamine, benzyltriethylamine, tribenzylamine, poly (4 vinylpyridine), calixarenes, tertiary amine-SO3 complexes, polyethyleneglycol, phenolformaldehyde resins, vinylimidazole, triethanolaminatotitanium, aminosilanes, phosphites, metal acetylacetonates, N-(oxydiethylene) benzothiazole-2-sulfenamide, bismuth dlmethyldithi ocarbonate, as well as alcohols, bases and hydroxyl or amine group containing compounds.
They could also be cationic polymerization initiators.
Free-radical polymerization initiators such as methylethylketone peroxide, cyclohexyl peroxide, cumene hydroperoxide, dibenzoyl peroxide or redoxy systems for generating free-radicals can be used. They are well known in the art of polymerizing acrylate and methacrylate monomers. Compounds which generate radicals or ions under ultraviolet or electron-beam irradiation could also be used to initiate polymerization of the reactive monomers of the present invention. The various initiators could be used alone or in conjunction with each other. In order to impart desired properties te the monomers of the present invention and to the properties of the resultant adhesive bond or polymer as well as for economic considerations, further additives can be introduced into them. They can be, for example, any of the known polymeric thickeners and viscosity regulators, rubbers, plasticizers and tougheners, compatibilizers, thixotropic agents, colourants, deodorants or perfumes, for example, used in cyanoacrylate adhesives and in acrylic and methacrylic ester compositions and polymers. The composition may also contain other monomers containing a reactive double bond.
A distinctive feature of the reactive monomers of the present invention is that they are easily polymerizable in a variety of ways. Anionic initiation, most commonly
Induced by the adsorbed on the objects' surface moisture causes polymerization along the dienic double bonds, yielding a polymer of substituted butadiene structure. The pendant acrylic or methacrylic double bonds can be additionaily polymerized by heat, redoxy systems or UV or
EB irradiation to yield a cross-linked elastomeric structure. In a different route of curing the acrylic or methacrylic double bonds could be polymerized initially yielding a polymethacrylate or polyacrylate with pending cyanopentadienic double bonds. They in turn could be polymerized by heat or moisture to produce similar to the first instance ross-iinked structure. The following scheme illustrates the curing reaction that the monomers of the present invention could undergo.
A distinctive feature of the reactive monomers of the present invention is that as a result of polymerization they can form strong adhesive bonds between a variety of substrates, ie metals, plastics, rubbers, glass, wood, paper, live soft or bone tissue. They can cure in a matter of seconds to minutes. Depending on the type and degree of cure the adhesive bond can vary from soft and rubbery to tough and resilient. A distinctive characteristic of the adhesive bond is that as a consequence of cross-linking it is water and humidity resistant, heat resistant, impact and peel resistant and can sustain large loads and stresses.
Application of the reactive monomers of the present invention is in structural and industrial adhesives.
Another distinctive feature of the reactive monomers of the present invention is that they spread easily over water or biological fluids and then form a polymeric layer. This property can be employed to utilize these monomers as medical and surgical adhesives, particularly for bonding bone tissue in which case the initial anionic polymerization could be followed by radical cross-linking to obtain cross-linked adhesive bond capable of sustaining the loads at the fractured interface.
Another application of the reactive monomers of the present invention is for coatings which can be produced by surface moisture cure or by UV-light irradiation. They will be particularly suitable for optical fibre coating.
Another application of the reactive monomers and polymers thereof of the present invention is for manufacture of positive or negative photo or electron beam resists. Their controlled step-wise polymerization will produce ultra-high resolution.
The above-mentioned applications are only indicative and do not limit the scope of application of the reactive monomers of the present invention, as well as the applications of their adhesives and polymers.
The invention is illustrated by the following examples:
Example 1 21.9g of methacryloyloxyethyl cyanoacetate is mixed together with 40ml of tetrahydrofuran. The mixture is cooled to 4"C and 9g of zinc chloride is added during mixing. The mixture is cooled again to 4" and 8.9ml of acrolein are added dropwise over 5 minutes. The temperature increases from 4"C to 8"C. The reaction flask is removed from the ice water bath and left stirring for 8 hours at room temperature. To the clear yellow solution obtained 50ml of toluene is added. The product is isolated by three consecutive extractions with 100ml of 2N hydrochloric acid. The organic layer is filtered through filter paper. The filtrate is stripped from the solvent by heating (90 C) under reduced pressure (0.7mmHg). A steady stream of air through a capillary is maintained during the stripping stage. 23.0g of methacryloyloxyethyl 2 cyanopenta-2,4-dienoate are obtained. Its n20 = 1,5139. IR
D spectrum (Figure 2) confirms the structure. A drop of the product placed on water spreads and forms a polymeric film.
A drop of product placed between fingers, glass or metal surfaces polymerizes instantly to give an adhesive bond.
Trample 2 35.2g of methacryloyloxypropyl cyanoacetate is mixed with 50ml of dioxane. 13.5g of zinc chloride is added during mixing. 13,25g of acrolein are added dropwise over 10 minutes, taking care the reaction temperature not to exceed 20"C. The stirring is continued for a further 8 hours at room temperature yielding a clear yellow solution. 100ml of methylmethacrylate are mixed in and then three consecutive extractions with 150ml of 2N hydrochloric acid are performed. The organic layer is filtered and stripped under reduced pressure (0.7mm Hug). The pot temperature is not to exceed 90 C and a steady stream of air through the product is maintained during stripping. 25g of methacryloyloxypropyl 2-cyanopenta-2, 4-dienoate are obtained with nD = 1,5045. The IR spectrum (Figure 3) D confirms the chemical structure. The product possesses the same adhesive properties as described in Example 1.
Example 3 20.4g of acryloyloxyethyl cyanoacetate containing 0.02g of p-methoxyphenol are mixed together with 40ml of tetrahydrofuran. Through a capillary a constant flow (4ml/ min) of dry air is sparged through the reaction mixture during the reaction. The mixture is cooled to 4"C and 9.5g of zinc chloride are added during mixing. The mixture is cooled again to 4"C and 8.9ml of acrolein are added dropwise over 5 minutes. The reaction temperature increases to 9"C.
The reaction flask is removed from the ice water bath and left stirring for 8 hours at room temperature. To the clear yellow solution obtained 50ml of toluene are added and the product is isolated by three consecutive extractions with looms of 2N hydrochloric acid solution.
The organic layer is filtered and stripped from solvents by heating up to 90"C under reduced pressure of 0.7mm Hg. A stream of air through a capillary is maintained during the stripping stage. 13.3g of acryloyloxyethyl 2-cyanopenta2,4-dieonate with n20 = 1,5147 are obtained. The IR
D spectrum (Figure 4) confirms the chemical structure.
Example 4 23.17g of methacryloylhexa(oxyethyl) cyanoacetate containing 0.035g of hydroquinone are mixed together with 33ml of dioxane. Through a capillary a constant flow (4ml/min) of dry air is started and maintained during the reaction process. 4.5g of zinc chloride are added during stirring. The mixture is cooled to 20 C and 4.45m1 of acrolein are added dropwise over 5 minutes. The mixing is continued at room temperature for 12 hours. To the clear yellow solution 100 ml of methyl methacrylate are added.
The product is isolated by three consecutive extractions with 100ml of 2N hydrochloric acid solution. The organic layer is filtered and subjected to stripping by heating up to 90"C under vacuum of 0.7mm Hg and the essential stream of dry air. 18g of methacryloyl(oxyethyl) 2-cyanopenta-2,4dienoate with n20 = 1,4964 are obtained. The IR spectrum (Figure 5) confirms the chemical structure.
