Abstract
A polymeric composition may include a polyolefin or styrenic polymer, a metallic acrylate salt, and an acid neutralizer.
Claims20
A polymeric composition comprising:
- a polypropylene or styrenic polymer;
- a metallic acrylate salt;
- and
- one or more acid neutralizers, wherein the one or more acid neutralizers are present in an amount greater than or equal to a weight percentage of the metallic acrylate salt and in an amount sufficient to reduce an amount of acrylic acid by at least 75% as compared to the polymeric composition without the one or more acid neutralizers.
1 more element
(canceled)
A foam comprising
- more than 50 weight % of a polypropylene or styrenic polymer;
- at least 1% metallic acrylate salt;
- and
- at least 1% one or more acid neutralizers, wherein the one or more acid neutralizers are present in an amount greater than or equal to a weight percentage of the metallic acrylate salt and in an amount sufficient to reduce an amount of acrylic acid by at least 75% as compound to the polymeric composition without the one or more acid neutralizers.

A process comprising:
- supplying a polymeric composition comprising a metallic acrylate salt, one or more acid neutralizers, and more than 50 weight % of a polypropylene or styrenic polymer resin, wherein the one or more acid neutralizers are present in an amount greater than or equal to a weight percentage of the metallic acrylate salt and in an amount sufficient to reduce an amount of acrylic acid by at least 75% as compared to the polymeric composition without the one or more acid neutralizers;
- and
- mixing the polymeric composition and a foaming agent to form a polymer foam.
