Abstract

PURPOSE: A mixture of a vinyl monomer such as styrene with a specific amount of aliphatic bis-amide is polymerized and impregnated with a foaming agent, then heated, thus giving foamed articles free from deformation and fissure in a shortened time of cooling on molding.
CONSTITUTION: In the suspension polymerization of (A) vinyl monomer mixture containing more than 50wt% of styrene in an aqueous medium, 0.01wt%, based on the monomer mixture or more, preferably 0.05W0.2%, of (B) aliphatic bis- amide such as ethylenebis-stearoamide. At the latter half of the polymerization or after the completion, (C) a foaming agent such as butane is added to the polymer by more than 5% and the resulting product is heated at 60W95, preferably 80W 90°C for 30W120min.
