Odor emission reduction for aqueous protective vinyl aromatic 1,3-diene copolymer dispersion involves adding 1-8C alkyl esters of mono- or dicarboxylic acids at end of emulsion polymerization

摘要

Odor emission reduction process for aqueous protective colloid-stabilized vinyl aromatic 1,3-diene copolymer dispersion and the obtained redispersion powder comprises adding 0.01-15 wt.% monomer(s) from 1-8C alkyl esters of mono- or dicarboxylic acids at the end of the emulsion polymerization, when the free monomer content is 0-20 wt.%.
