A process for forming a polymeric composition comprising melt blending a polylactic acid with a reactive modifier selected from epoxy-functionalized polybutadiene, ionic monomer, and combinations thereof to form a modified polylactic acid during a first step and, subsequently melt blending the modified polylactic acid with a polyolefin to produce a polyolefin-polylactic acid blend during a second step.
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;
- contacting the polylactic acid and the reactive modifier with a polyolefin to produce a polyolefin-polylactic acid blend;
- and
- combining the polyolefin-polylactic acid blend with a second polyolefin and a polyester thereby forming a second blend.
A process comprising:
- forming a polymeric composition comprising contacting a polylactic acid with a reactive modifier selected from epoxy-functionalized polybutadiene, ionic monomer, and combinations thereof;
- contacting the polylactic acid and the reactive modifier with a polyolefin to produce a polyolefin-polylactic acid blend;
- and
- forming a multilayer film having a polyolefin layer, a polyester layer, and a tie layer disposed between the polyolefin layer and the polyester layer, wherein the tie layer comprises the polyolefin-polylactic acid blend.
