Novel vinyl ethers, process for their preparation, and their use for the preparation of polymers

Claim 1

An addition polymer which consists essentially of (a) from 0.005 to 100 mol percent of repeating units derived from a hydantoin vinyl ether of the formula I ##STR20## in which R 1 is hydrogen, phenyl, methyl, cyanoethyl, glycidyl, hydroxymethyl, hydroxyethyl, hydroxypropyl, acetyl, 2-hydroxy-2-phenyl-ether or ##STR21## R 2 is an alkylene group having 1 to 6 carbon atoms or the (-alkylene-O-)n-alkylene- group, in which the alkylene groups contain 1 to 6 carbon atoms and n is a number from 1 to 6, and R 3 and R 4 independently of one another are each hydrogen, an alkyl group having 1 to 6 carbon atoms, or together are a tetramethylene or pentamethylene group, and (b) from 99.995 to 0 mol percent of repeating units derived from one or two monomers selected from the group consisting of vinyl acetate, acrylonitrile, vinyl ethers, diketene, anhydrides of α,β-unsaturated dicarboxylic acids and styrene.
