This invention relates to a method of producing modified vinyl ether polymers, wherein vinyl ether polymers comprising recurring units of general formula (I) (see formula I) where R represents a C2 - C4 alkyl group and x denotes an integer from 10 to 1000, are partially transetherified with compounds of general formula Y-OH, wherein Y represents aliphatic and/or cycloaliphatic hydrocarbon groups comprising 5 to 30 carbon atoms, the hydrogen atoms of which can be replaced at least in part by halogen atoms and/or aryl radicals, and/or represents aliphatic, cycloaliphatic and/or aromatic groups with a molecular weight of up to 6000 which contain at least one ether group -O- or an ester group -COO- within the molecule, in the presence of compounds of the platinum metals with the release of the corresponding C2 - C4 alcohols, wherein statistically at least one R radical is replaced by a Y radical per molecule of vinyl ether polymer.
