摘要

The invention relates to the use of vinyl phosphonic acid or a salt thereof for improving the biodegradability of mixed polymers, comprising 25 to 99.5% by weight of structural units of one or more monomers selected from the group made of compounds of formula (1) and formula (3),; embedded image ;where R1 and R2 independently are hydrogen or C1-C4-alkyl, formula (4), where n is 3, 4, or 5, and formula (5),; embedded image ;where X is OH or for NR3R4, and R3 and R4 independently are H or C1 to C4-alkyl, in that 0.5 to 25% by weight of vinyl phosphonic acid is polymerized into the mixed polymer.
