ABSTRACT:
A method for improving the expandability of styrenic polymer particles is disclosed. The method comprises copolymerizing a styrenic monomer with an amount of an acrylate monomer effective to improve the expandability of the particles without adversely affecting their heat sensitivity. Polymer foams of low density can be prepared with reduced amounts of blowing agents.
