Abstract

PURPOSE: To obtain title polymer particles having fine foam within the particles during prefoaming stage, by a method wherein a blowing agent and a small amount of a mercaptan cpd. or a mercaptocarboxylic acid as a foam stabilizer are incorporated into styrene polymer particles.
CONSTITUTION: There are provided expandable styrene polymer particles obtained by incorporating (B) 0.0001W0.01pt.wt. of at least one cpd. selected from (a) mercaptan cpd. of formula I (wherein R1 is 3W16C alkyl, aryl) or (b) mercaptocarboxylic acid and ester thereof having formula II (wherein R2 is 1W3C alkylene, R3 is H, 1W16C alkyl) and (C) 1W20pts.wt. of a blowing agent consisting of hydrocarbon having a b.p of not higher than the softening point of the styrene polymer particle, into (A) 100pts.wt. of the styrene polymer particles.
