Abstract

There are disclosed a gel or polymer composition which comprises 100 parts by weight of: a graft copolymer composition formed from the graft reaction of a maleate functionalized ethylene-alpha-olefin copolymer and a maleate functionalized polypropylene with an organic diamine grafting agent, and at least 30 parts by weight of an extender oil or a low molecular weight organic component. These gel compositions have super soft properties, heat resistance, and/or damping properties.
