Abstract
A vulcanized rubber is formed by a method comprising blending a halogenated unsaturated polymer into a rubber comprised of cis 1-4 polyisoprene to form a vulcanizable polymer blend, adding a vulcanization material to the vulcanizable polymer blend, and vulcanizing the vulcanizable polymer blend to form a homogeneous vulcanized rubber. The method may be used to form a vulcanized rubber comprised of polyisoprene uniformly crosslinked with a halogenated unsaturated polymer that is a reaction product of (i) an unsaturated polymer miscible with polyisoprene and having conjugated dienes that undergo a Diels Alder reaction and (ii) a polyhalogenated cyclopentadiene.

A vulcanized rubber comprised of polyisoprene uniformly crosslinked with a halogenated unsaturated polymer that is a reaction product of (i) an unsaturated polymer that is miscible with polyisoprene and has conjugated dienes that undergo a Diels Alder reaction and (ii) a polyhalogenated cyclopentadiene represented by:
- wherein X is a fluorine, chlorine or bromine and Y is fluorine, chlorine, bromine or alkoxy having 1 to 4 carbons.
