    Abstract: An improved silane modified polymer useful in adhesive compositions is made from a silane precursor material made by a process comprising reacting an organic compound having a backbone that is terminated by an amino group having at least one active amino hydrogen and a hydrolysable silane, wherein the backbone is comprised of at least one secondary amino group having one active amino hydrogen and a Michael addition acceptor compound, wherein the Michael addition compound fails to have a group reactive with an isocyanate group to form the silane precursor compound. The silane precursor compound is reacted with an isocyanate terminated polyurethane prepolymer to form a silane modified prepolymer. The silane modified prepolymer may then be cured with moisture and may be employed in an adhesive composition containing other components such as a plasticizer, catalyst and filler.

    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.
