  • Patent number: 10920118
    Abstract: Disclosed is a composition comprising: a) an condensate of one or more aminohydrocarbyl alkoxy silanes and one or more alkenyl alkoxy silanes; b) one or more mercaptohydrocarbyl alkoxy silanes; and c) water; wherein the composition is useful as a primer useful with adhesives or coatings containing polymers having isocyanate functional groups, alkoxysilane functional groups or both. The composition may include one or more epoxyhydrocarbyl silanes. The composition may include one or more alkanols in sufficient amount to improve the volatilization of the liquid components away from substrate surface.
    Type: Grant

  • Patent number: 10189960
    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.
    Type: Grant

  • Patent number: 5494758
    Abstract: An article is provided manufactured by an ion-beam-assisted-deposition process. The article includes a polymeric element adapted to releasably engage a contact surface. The polymeric element is provided with a surface layer bonded to a surface of the polymeric element through an ion-beam-assisted-deposition process in order to reduce the tackiness of the polymeric material.
