Abstract
PURPOSE: Titled particles obtained by polymerizing specific monomers included in styrene polymer particles and adding no organic foaming agent to the resultant particles, thus showing no foaming uneveness at the surface and inner side of the particles and no fuse at the surface and having high mechanical strength because the cohesion between particles is good.
CONSTITUTION: (A) (a) 97W50wt% of particles of styrene polymer such as polystyrene is impregnated with (b) 3W50wt% of styrene monomer such as α-methylstyrene and 0.4W5wt% of cetyl methacrylate so that the total of components a+b+ c becomes 100wt%. The resultant particles are polymerized in an aqueous medium in the presence of a catalyst such as organic peroxide and an organic foaming agent such as propane is added to the resultant particles, preferably by 1W10wt% based on the polymer particles.
