Abstract
A styrenic composition including a polar modified styrenic co-polymer resulting from the polymerization of a combined mixture of at least one styrenic monomer and at least one comonomer and a biodegradable component is disclosed. The at least one comonomer includes a polar functional group and the polar modified styrenic co-polymer and the biodegradable component are combined to obtain a styrenic composition having a biodegradable component. Also disclosed is a method of enhancing bio-polymer miscibility in a styrenic based polymer. The polarity of a blend is manipulated by combining a styrenic monomer and a polar co-monomer to form a combined mixture and subjecting the combined mixture to polymerization to obtain a styrenic polymer blend to which a bio-polymer is added.
