摘要

- 33 - O.Z. 0050/40679 A graft (co)polymer comprises at least one unit of the general structure or where ¢M!x is a polymeric side chain formed by free radical homopolymerization or copolymerization from x monomer units, x is from 10 to 100,000, E and A are each copolymerized linear segments of a chain molecule, and m and p are each at least 1 and together more than 100 (denoting the degree of polymerization), the substituents R1, R2 and R3 each being alkyl, aryl or hetaryl or equivalents thereof and R2 and R3 being identical to or different from each other, is obtained by addition of a 4-substituted 1,2,4-triazoline-3,5-dione or an azodicarboxylic ester to a linear chain molecule segment having an allylic CH group or mobile protons.
