Abstract (en)
[origin: WO2009065162A2] The invention relates to a polymerisable composition for the production of biodegradable, biocompatible, cross-linked polymers on the basis of polyvinyl alcohol, comprising: 5-100 % by weight vinyl ester monomer(s) of general formula (I), (II) or (III), in which X represents oxygen, sulphur, nitrogen or phosphor, n = 1-1000, at least 20% of n =2, R1 is selected from hydrogen, unbranched, branched or cyclic, saturated or unsaturated, n-valent hydrocarbon groups comprising 1-30 carbon atoms, which optionally have heteroatoms and are optionally substituted by substituents selected from -OH, -COOH, -CN, -CHO and =O and from n-valent groups of biodegradable, biocompatible oligomers and polymers, m = 1-5, R2 is selected from hydrogen, -OH, =O and the options for R1 and R3 is selected from hydrogen, -OH and the options for R1; 0-50 % by weight of ethylenically unsaturated comonomers; 0-10 % by weight of polymerisation initiator(s); and 0-95 % by weight of solvents.
