Abstract:
A method of making a foamable polystyrene composition includes combining a styrenic monomer and a co-monomer containing a polar functional group to obtain a mixture, subjecting the mixture to polymerization to obtain a styrenic co-polymer, and combining the styrenic co-polymer with a blowing agent in a foaming process to obtain foamed articles.
