Abstract
Official abstract text for this publication.
The present invention relates to polymeric compositions comprising polylactic acid (PLA), polyolefin, and, optionally, a non reactive melt strength enhancing additive (NRMSEA), as well as articles molded from the compositions and a method of making the compositions.
First claim
Opening claim text (preview).
What is claimed is: 1. A polymeric composition consisting of: (a) about 10 wt % of a polylactic acid polymer; (b) about 88.8 wt % of an HDPE copolymer; (c) about 1.2 wt % of an ethylene acrylate copolymer. 2. A polymeric composition consisting of: (a) about 5 wt % of a polylactic acid polymer; (b) about 94.4 wt % of an HDPE copolymer; (c) about 0.6 wt % of an ethylene acrylate copolymer. 3. A polymeric composition consisting of: (a) about 5 wt % to about 6 wt % of a polylactic acid polymer; (b) about 94 wt % to about 95 wt % of an HDPE copolymer; (c) about 0.6 wt % ethylene acrylate copolymer; wherein the ethylene acrylate copolymer is present in the polymeric composition in a weight ratio of about 0.12 with the polylactic acid polymer. 4. An article manufactured from said polymeric composition of claim 3 . 5. The article of claim 3 , wherein said article is a container.
