Abstract
Official abstract text for this publication.
A pellet composed of a polymeric blend having a polyolefin and polylactic acid.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pellet comprising: a polymeric blend comprising a polypropylene matrix comprising a propylene impact copolymer, polylactic acid phases comprising a polylactic acid, rubber phases comprising a rubber, and an epoxy functionalized polyolefin, wherein the epoxy functionalized polyolefin is epoxy functionalized polypropylene or epoxy functionalized polyethylene, wherein the polylactic acid and the epoxy functionalized polyolefin are premixed before being compounded with the propylene impact copolymer, and wherein the polylactic acid phases are encapsulated inside the rubber phases in the polypropylene matrix, and wherein the polymeric blend comprises from 51 to 99.5 weight percent of the propylene impact copolymer and from 0.5 to 49 weight percent of the polylactic acid based on a total weight of the polymeric blend. 2. The pellet of claim 1 , wherein the epoxy functionalized polyolefin is epoxy functionalized polyethylene. 3. The pellet of claim 1 , wherein the epoxy functionalized polyolefin is epoxy functionalized polypropylene. 4. The pellet of claim 1 , wherein the epoxy functionalized polyolefin is PP-g-GMA or PE-co-GMA. 5. The pellet of claim 1 , wherein the rubber is ethylene propylene diene rubber (EPDM).
