ABSTRACT:
A method of preparing a thermoplastic elastomeric blend comprising mixing from 90 to 10 parts by weight of monoolefin copolymer rubber with correspondingly from 10 to 90 parts by weight of polyolefin resin having tertiary hydrogen and a free radical generating curing agent therefor, masticating and shearing the mixture to produce a semi-cure of the rubber, completing the semi-cure before the onset of melting of the polyolefin resin, and ensuring that once the polyolefin has melted the level of free radicals remaining in the mixture is not sufficient to cause substantial degradation of the polyolefin.
