1-25. (canceled)
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 polymeric composition comprising:
- a polylactic acid;
- a reactive modifier selected from epoxy-functionalized polybutadiene, ionic monomer, and combinations thereof;
- and
- a polyolefin that exhibits a melt flow rate of less than about 6 dg/min.
