Abstract
There is disclosed a gel or polymer composition containing: 100 parts by weight of a graft copolymer composition formed by the reaction of an organic diamine grafting agents with maleate functional groups on an elastomeric block containing block copolymer and with maleate functional groups on polypropylene, 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.
