Abstract

PURPOSE: To obtain title polymer particles for which mutual melt adhesion of particles are prevented, by a method wherein, in suspending PS particles in the presence of a surface active agent and impregnating a foaming agent having b.p. of below a softening point of said polymer, a minute amount of PVA is added.
CONSTITUTION: In suspending styrene polymer particles (A) in water (C) in the presence of a surface active agent (B) and impregnating a foaming agent (D) having b.p. of below softening point of (A), 5W100ppm to (A) of PVA is added and a foamable styrene polymer (F) is prepared. Herein, as (A), a polymer obtained by subjecting a styrene monomer or a styrene monomer and a copolymerizable monomer therewith to suspension polymerization is preferred. Moreover, as (B), a nonionic active agent such as aliphatic acid soap or alkylarylsulphonate and, as (D), propane, pentane or the like are mentioned.
