Abstract
Polymer articles including maleic anhydride are described. The articles have improved characteristics and properties, such as surface bonding properties, even when the article includes a large percentage of ethylene propylene diene monomer terpolymer, ethylene-vinyl acetate, ethylene-acrylic elastomers, reclaim, or an oil.
Claims53
A method of making a foamed article comprising:
- providing a mixture including a first polyolefinic polymer, an oil, and maleic anhydride, the maleic anhydride being grafted to a portion of the mixture and the mixture including greater than 25 weight percent of the oil;
- cross-linking the mixture sufficiently to form a flexible article having low tackiness;
- and
- expanding the mixture to form a foamed article.
A foamed article comprising a mixture including a first olefinic polymer, an oil, and maleic anhydride grafted to a component of the mixture, wherein the mixture is cross-linked sufficiently to provide a flexible article having low tackiness, and the mixture includes greater than 25 weight percent of the oil.
A polymer article comprising a mixture comprising an ethylene-acrylic polymer, an oil, and a maleic anhydride grafted to a portion of the mixture, the mixture including greater than 25 weight percent of the oil.
