POLYMER AND METHODS FOR MANUFACTURING IT

Document Type and Number:

WIPO Patent Application WO/2020/133034

Kind Code:

A1

Abstract:

The invention relates to a polymer having a main chain which is obtained by free radical emulsion polymerisation of a monomer mixture, which comprises at least one optionally substituted styrene, at least one C1 –C4 alkyl (meth) acrylate and at least one ethylenically unsaturated monomer. The monomer mixture is polymerised in a reaction mixture comprising a natural and/or synthetic polymeric stabilator. According to the invention the polymer main chain further comprises a reaction product of silica sol and an unsaturated organosilicon compound. The invention relates also to methods of making such polymer.
