Abstract
A method of making a styrenic composition having a high melt strength including combining a styrenic monomer and a second monomer to form a combined mixture and subjecting the combined mixture to polymerization to obtain a styrenic co-polymer, wherein the second monomer comprises a hydroxyl functional group and wherein the styrenic composition has a greater melt strength than that of general purpose polystyrene.
