Abstract

PURPOSE: To enable the stable and high expansion foaming under arbitrary conditions between atmospheric pressure and high pressure, by impregnating a foaming agent to particles prepared by polymerizing a styrene-type monomer, diallyl phthalate, and an acrylic acid ester or methacrylic acid ester.
CONSTITUTION: A foaming agent pref. a mixture of isobutane, etc. and other foaming agent, is impregnated in particles obtained by the polymerization of (A) a styrene-type monomer containing ≥50wt% of styrene, (B) diallyl phthalate, and (C) an acrylic acid ester or a methacrylic acid ester which gives a polymer having the second order transition point of ≤0°C when homopolymerized. The amount of the diallyl phthalate is 0.05W3wt% based on the raw materials of the resin as a whole, and that of the acrylic or methacrylic acid ester is 0.5W10wt%. The weight ratio of the diallyl phthalate to the (meth)acrylic acid ester is 1 to 3W10.
EFFECT: The composition does not shrink even after preliminary foaming.
