Using Hybridcopolymeren as protective colloids for polymers
2012
The invention relates to the use of Hybridcopolymeren as protective colloids for polymers based on ethylenically unsaturated monomers (base polymers), characterized in that the Hybridcopolymere are obtainable by A) free-radically initiated polymerization of one or more ethylenically unsaturated monomers a) selected from the group comprising Vinylester of carboxylic acids having 1 to 15 carbon atoms, methacrylic esters or acrylate of carboxylic acids having branched or unbranched, optionally substituted alcohols having 1 to 15 carbon atoms, Methacrylsaureeamide or acrylamides of amines with unbranched or branched, substituted or unsubstituted amines having 1 to 15 C atoms, olefins and dienes, vinylaromatics and vinyl halides and optionally, one or more silanes b) is selected from the group of ethylenically unsaturated silanes and mercaptosilanes in the presence of one or more water-soluble polymer c) and optionally thereafter B) condensation of one or more silicon compounds of the general formula (RO) or of one or more condensation products of the formula (1), in which R is an optionally substituted alkyl or aryl radical having 1 to 20 carbon atoms or a hydrogen atom, R n is 1-4 assumes.
