FOAMED ARTICLES OF STYRENIC AND ACRYLIC POLYMERS BLEND

摘要

Foamed articles having a closed cell structure formed from a polymer blend comprising at least 50 % by weight of a styrenic polymer and up to 50 % by weight of an acrylic polymer which has an average molecular weight which is less than 90 % of that of the styrenic polymer which are significantly less dense than such articles prepared from the styrenic polymer alone.
