Abstract

PURPOSE: To obtain polymer particles having rough surfaces and an increaced surface area, by polymerizing a monomer mixture containing an aromatic vinyl compound and a cyanoethylene compound at a specified monomer/water ratio or at a specified combination.
CONSTITUTION: A monomer mixture consisting of 50W90wt% aromatic vinyl compound, 10W40wt% cyanoethylene compound, 0W15wt% α,β-ethylenically unsaturated carboxylic acid and 0W20wt% other vinyl compounds copolymerizable therewith is polymerized by batchwise or continuous charge emulsion polymerization. In case of the batchwise monomer charge, the particle shape varies with a monomer to water ratio, and it is spherical at high monomer to water ratio. Therefore, the polymerization is carried out at a monomer to water ratio of 0.01W0.1. In case of the continuous charge, at conversions <80%, particles with rough surfaces are hardly obtained, and so the polymerization is carried out so that the conversion is always maintained at 80% or higher.
