Abstract
Polymeric compositions and processes of forming the same are discussed herein. The processes generally include contacting a polylactic acid with a reactive modifier selected from epoxy-functionalized polybutadiene, ionic monomer, and combinations thereof.
Claims13
A process for forming a polymeric composition comprising:
- contacting a polylactic acid with a reactive modifier selected from epoxy-functionalized polybutadiene, ionic monomer, and combinations thereof;
- and
- contacting the polylactic acid and the reactive modifier with a polyolefin to produce a polyolefin-polylactic acid blend, wherein the polyolefin exhibits a melt flow rate of less than about 6 dg/min.
A process comprising:
- forming a polymeric composition by contacting a polylactic acid with a reactive modifier selected from epoxy-functionalized polybutadiene, ionic monomer, and combinations thereof;
- processing the polymeric composition using one or more polymer processing techniques selected from:
- film, sheet, pipe extrusion or coextrusion, blow molding, injection molding, rotary molding, and thermoforming.
