Abstract:
1. A method for making a shaped item adapted for an article comprising said shaped item, said method comprising: (a) admixing a dispersed phase of a plurality of vulcanized elastomeric portions into a continuous phase of thermoplastic polymer to form an admixture composition, said dispersed phase of vulcanized elastomer vulcanized to provide a compressive set value from about 50 to about 100 percent of the difference between a non-vulcanized compressive set value for said elastomer and a fully-vulcanized compressive set value for said elastomer; (b) forming said composition into said shaped item; and (c) cross-linking said continuous phase, wherein said cross-linking inter-bonds said continuous phase and said dispersed phase with at least one inter-bonding molecule corresponding to the formula  wherein A is an elastomeric moiety from a free radical polymeric derivative derived from said elastomer of said dispersed phase, said elastomeric moiety having a collective atomic weight of from about 350 to about 10,000,000, and D is a polymeric carbon chain thermoplastic moiety, said polymeric carbon chain thermoplastic moiety from a free radical polymeric derivative of a thermoplastic molecule from said continuous phase, said thermoplastic molecule having a molecular weight of from about 120 to about 10,000,000.
