METHOD FOR PRODUCING GRAFT POLYMERS

摘要

The invention relates to a method for producing graft polymers, comprising the following steps: 1. Bringing the following into contact with each other: at least one source of free radicals; at least one compound of formula (I); at least one monomer M1 selected from 1,1 disubstituted ethylenically unsaturated monomers; 2. Then bringing the polymer resulting from the polymerisation in step 1 into contact with the following: at least one source of free radicals and at least one ethylenically unsaturated monomer M2, the proportion of radically polymerisable 1,1 disubstituted ethylenically unsaturated monomers being more than 90 wt. % in relation to the total of M2 monomers.
