Composition that can be cured by polymerisation for the production of biodegradable, biocompatible, cross-linkable polymers on the basis of polyvinyl alcohol
The present invention relates to a polymerization-curable composition for the preparation of biodegradable, biocompatible, cross-linked polymers on the basis of polyvinyl alcohol comprising: 5 to 100% by weight of (a) vinyl ester monomer(s) of one of the general formulas (I) to (III):wherein X is oxygen, sulfur, nitrogen, or phosphorus； n is 1 to 1000, at least 20% of the n being ≧2； the R1 are selected from hydrogen； straight, branched or cyclic, saturated or unsaturated, n-valent hydrocarbon groups having 1 to 30 carbon atoms, which optionally have heteroatoms and are optionally substituted with one or more substituents selected from —OH, —COON, —CN, —CHO, and ═O, and n-valent radicals of biodegradable, biocompatible oligomers and polymers； m is an integer from 1 to 5； the R2 are selected from hydrogen, —OH, ═O, and the options listed for R1； and the R3 are selected from hydrogen, —OH, and the options listed for R1； 0 to 50% by weight of ethylenically unsaturated co-monomers； 0 to 10% by weight of (a) polymerization initiator(s)； and 0 to 95% by weight of solvent(s).
