Polarity Manipulation In Polystyrene For Enhanced Bio-polymer Miscibility
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.

- 21. A styrenic composition comprising:
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; a biodegradable component comprising polylactic acid; and a polar additive comprising styrene maleic anhydride, glyceride oil, poly(1,4-butylene adipate), epoxidized linseed oil, polyester, or combinations thereof; wherein the at least one comonomer comprises a polar functional group; wherein the polar modified styrenic co-polymer and the biodegradable component are combined to obtain a styrenic composition comprising the biodegradable component.
- 27. A method of making a styrenic polymer comprising a biodegradable component comprising:
combining a styrenic monomer and a comonomer comprising a polar functional group to form a combined mixture; subjecting the combined mixture to polymerization to obtain a polar modified styrenic co-polymer; and combining the polar modified styrenic co-polymer with a biodegradable component and a polar additive to obtain the styrenic polymer comprising the biodegradable component, wherein the biodegradable component comprises polylactic acid, and wherein the polar additive comprises poly(1,4-butylene adipate), epoxidized linseed oil, or combinations thereof.
