Definitions
- the invention relates to terminally unsaturated, oxetane-based macromonomers and to a process for their preparation.
- Macromonomers are oligomers or polymers having at least one functional end group through which polymerization reactions can take place. Macromonomers are thus macromolecular monomers that can be converted to homopolymers or copolymers of defined structures. For example, macromonomers having an ethylenically unsaturated end group can be reacted by radical polymerization to graft copolymers or comb polymers having a defined length of the side chains.
- WO 02/40572 A1 describes a process for preparing dendritic polyethers having a core derived from a compound having two or more hydroxyl groups and at least one branching generation obtainable from at least one hydroxyoxetane.
- the core of the dendritic polyether may contain one or more allyl groups.
- allyl groups have only a comparatively low reactivity in radical polymerization reactions.
- WO 00/56802 A1 describes the synthesis of hyperbranched dendritic polyethers which are obtainable by thermally initiated cationic ring opening of oxetane monomers having at least two functional groups.
- the terminal hydroxy groups of the hyperbranched dendritic polyethers obtained can then be further reacted, for example by functionalization with epoxy, allyl or acrylate groups.
- no defined polyethers can be obtained, each of which contains only one free-radically polymerizable group per molecule.
- the free-radical polymerization of such macromonomers containing several free-radically polymerizable groups per molecule entails the risk of undesired crosslinking reactions.
- the properties of the coating compositions or coatings and / or plastics should be able to be modified in a targeted manner.
- additives which are suitable as flow control agents and can improve, for example, the course, gloss and / or opalescence of the coating compositions or coatings or plastics.
- additives which give the coating compositions or coatings and / or the plastics an anti-adhesive surface, so that, for example, dirt, water and / or oil-repellent surfaces can be achieved.
- additives which are suitable as wetting and dispersing agents and can, for example, lower the viscosity of pigmented and / or filler-containing coating compositions and / or stabilize the dispersion of pigments and / or fillers in coating compositions.
- additives which give the coating compositions or coatings and / or the plastics improved wettability, so that, for example, surfaces which are easier to print and / or the adhesion of coatings is improved.
- Lots Coatings, polymeric molding compounds and thermoplastics have a non-polar surface with low surface energy. Therefore, the wetting of such surfaces by z.
- aqueous coating compositions printing inks, aqueous polymer dispersions, adhesives or adhesion promoters a challenge.
- the surface energy of the substrates must be increased by the use of additives, so that the substrate surfaces are made more polar. For this reason, there is a need for the development of corresponding additives for improving the wettability and thus, for example, the printability or paintability of various coatings, polymeric molding compounds and thermoplastics.
- the additives added for imparting these improved properties should as far as possible not impair the other properties of the coating compositions or coatings, polymeric molding compounds or thermoplastics.
- the added additives should also be able to develop their activity in relatively small amounts.
- the coatings, polymeric molding compounds and thermoplastics are said to continue to retain their improved surface properties over a long period of several years even in outdoor weathering. This should also include the permanence of the effects, for example the anti-adhesive and / or soil-repelling effect, over several cleaning cycles.

- Other possible derivatizations of the hydroxyl groups of the hydroxyoxetane include Williamson's ether synthesis, reactions with acid anhydrides or carboxymethylation.
- the divalent organic radical L contains no free-radically polymerizable groups. Free-radically polymerizable groups are understood as meaning functional groups which can be radically polymerized under customary conditions, for example ethylenically unsaturated groups.
- the radical L may be, for example, an alkylene, arylene or polyalkylene oxide radical.

- R 1 is alkyl, alkoxy, alkoxyalkyl, aryloxyalkyl, hydroxyalkyl, hydroxyalkoxy, hydroxyalkoxyalkyl, aryl, aryloxy, hydroxyaryl or hydroxyaryloxy

- Each R 3 is independently hydrogen, alkyl, alkoxy, alkoxyalkyl, aryloxyalkyl, hydroxyalkyl, hydroxyalkoxy, hydroxyalkoxyalkyl, aryl, aryloxy, hydroxyaryl or hydroxyaryloxy,
- the molar ratio (hydroxyoxetane (e) of the formula (I): starting molecule) is preferably from (50: 1) to (2: 1), more preferably from (25: 1) to (3: 1).
- the oxetane-based macromonomers according to the invention contain in each case one radically polymerizable group as head group per molecule. This makes it possible that in a subsequent radical homo- or copolymerization of macromonomers polymers are obtained with a defined comb structure. As is known, however, by-products are regularly produced in chemical syntheses. In the synthesis of the macromonomers according to the invention, therefore, small amounts of macromonomers having two or more free-radically polymerizable groups and small amounts of products without a radically polymerizable group can also be obtained. By means of the production process according to the invention, however, the proportions of such by-products can be kept very low.
- the macromonomers synthesized according to the invention therefore preferably have only very small, more preferably no fractions of molecules with no or more than one free-radically polymerizable group.
- the preparation of the macromonomers according to the invention by cationic oxetane ring-opening polymerization of the hydroxyoxetanes with the starting molecule is carried out at about 30 0 C to 130 0 C, preferably at about 50 ° C to 110 ° C, in the presence of at least one suitable catalyst.
- Suitable catalysts for the cationic oxetane ring-opening polymerization are, for example, Lewis acids, in particular AlCl 3 , BF 3 , TiCl 4 , ZnI 2 , SiF 4 , SbF 5 , PF 5 , AsF 5 or SbCl 5 , and, for example, halogenated acids, in particular FSO 3 H, CISO 3 H, HCIO 4 , HIO 4 or CF 3 SO 3 H, as well as other Bronsted acids (eg, para-toluenesulfonic acid, sulfonic acid).
- Lewis acids in particular AlCl 3 , BF 3 , TiCl 4 , ZnI 2 , SiF 4 , SbF 5 , PF 5 , AsF 5 or SbCl 5
- halogenated acids in particular FSO 3 H, CISO 3 H, HCIO 4 , HIO 4 or CF 3 SO 3 H, as well as other Bron
- onium salts for example a sulphonium, an oxonium and / or iodonium salt.

- examples of such compounds are benzyl tetramethylene sulfonium hexafluoroantimonate, Benzyltetramethylensulphonium- hexafluorophosphat and Benzyltetramethylensulphonium trifluoromethanesulphonate.
- the catalyst used is preferably CF 3 SO 3 H (trifluoromethanesulfonic acid), since the ethylenically unsaturated head groups of the starting molecule U-L-X-H are as far as possible not impaired during the cationic oxetane ring-opening polymerization, in particular not prematurely polymerized, but the unsaturated groups are as complete as possible should be preserved. This is facilitated by the use of a cationic polymerization catalyst, such as trifluoromethanesulfonic acid, which is gentle in this respect.
- the preparation of the macromonomers according to the invention preferably takes place in the presence of an inhibitor of free-radical polymerization.
- inhibitors of radical polymerization for example, hydroquinone or hydroquinone monomethyl ether are suitable.
- the free radical polymerization inhibitor is used to scavenge free radicals that could possibly form during storage or during the thermally assisted cationic ring-opening polymerization of the oxetane monomers, thus ensuring the stability of the ethylenically unsaturated, radically polymerizable head group U of the starting molecule .
- An advantage of using an inhibitor of radical polymerization is thus that the reaction is facilitated and less by-products occur.
- the hydroxyoxetane (s) are added slowly to the preheated reaction mixture which contains the starting molecule U - L - X - H and the at least one acidic catalyst, and preferably also the at least one free radical polymerization inhibitor.
- the slow addition of the hydroxyoxetane (s) gives better defined products.
- Solvents can be used. However, these must not influence the cationic oxetane ring-opening polymerization. Suitable solvents are, for example, those which contain no active hydrogen atoms, no polymerizable rings and no groups which could react with the hydroxyoxetane (in particular with the hydroxyl groups of the hydroxyoxetane), with the starting molecule or with the resulting oxetane-based macromonomer. Preference is given to using aliphatic, cycloaliphatic and aromatic solvents, ketones and blocked polyethers as solvents. The choice of the solvent also depends on the later intended use of a polymer to be synthesized following from the macromonomers. Low-boiling solvents are preferably used to facilitate distilling off in those applications where the polymers obtained later are to be used as a 100% formulation, e.g. in UV-curing coating systems.
- the product is cooled and neutralized by addition of a base or by treatment with a basic ion exchange resin. Any residual amounts of starting molecule, insofar as they interfere with the subsequent free-radical polymerization, can be removed by suitable distillative measures, e.g. by thin film evaporation.
- the implementation of the cationic ring - opening polymerization of hydroxyoxetanes with the starting molecule U - L - X - H is facilitated by the selection of certain starting molecules U - L - X - H.
- the reaction usually succeeds well with starting molecules from the group of esters of (meth) acrylic acid. In contrast, the reaction can be slightly more difficult when using appropriate amides or vinylbenzyl alcohols as starting molecules.
- the oxetane-based macromonomer can be further modified by polymer-analogous reactions before a subsequent radical polymerization. For example, free hydroxyl groups can be completely or partially esterified, for example with acetic acid.
- Esterification may be useful, for example, to avoid interlayer adhesion problems or to change the polarity of the polymer when using the polymers in paint systems.
- Free hydroxyl groups of the macromonomer (s) can also be reacted wholly or partly with isocyanates, for example with alkyl isocyanates.
- isocyanates for example with alkyl isocyanates.
- stearyl isocyanate By modification with longer-chain alkyl isocyanates, such as stearyl isocyanate, prior to the radical polymerization, the polarity of the polymer can be changed in the direction of hydrophobicity, so that use of the polymers in nonpolar thermoplastics is facilitated.
- an increase in the hydrophilicity and optionally improved solubility in water is achieved by reacting free hydroxyl groups of the macromonomer (s) prior to free-radical polymerization wholly or partly with hydrophilic compounds, for example with TDI monoadducts.
- hydrophilic compounds for example with TDI monoadducts.
- Suitable examples are monoadducts from the reaction of toluene diisocyanate (TDI) with methanol-started polyethylene glycol.
