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 stabilizer. 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.
