ABSTRACT:
Methods for preparing a shaped rubber article, comprising admixing at least one thermoplastic material and at least one elastomer material to provide a processable and dimensionally stable rubber composition, shaping the composition, and irradiating the composition to form the shaped rubber article. The dimensional stability of the uncured composition may be provided by partial dynamic vulcanization, high performance reinforcing fillers, fractional curing, or combinations thereof. The elastomer material is present in an amount greater than about 65% by weight based on the total weight of the thermoplastic and elastomer materials present in the admixture.
