    Abstract: The present invention provides melt-processible adhesive compositions prepared from a first oligomer containing reactive functional groups capable of reaction at effective rates (at normal processing temperatures) with a co-reactive second component oligomer possessing functionality that is complementary to that of the first oligomer. The compositions may be used as coatings, including hard surface coatings, clear coatings, powder coatings and pattern coatings; as adhesives, including pressure sensitive adhesives and hot melt adhesives; as sealants; as optical coatings; as blown microfibers (BMF); as high refractive index optical materials; as barrier films; in microreplication; as low adhesion backsizes, (LABs) and as release coatings.

  • Patent number: 6979714
    Abstract: The present invention provides an adhesion promoting agent which includes a graft copolymer formed by a halogenated polyolefin polymer with at least one reactive functionality and a substantially saturated hydrocarbon polymer having more than one reactive functionality. At least one reactive functionality of the saturated hydrocarbon polymer is reactive with the reactive functionality of the halogenated polyolefin to form the graft copolymer of the invention.

  • Patent number: 6872780
    Abstract: A butyl polymer composition having improved cold flow properties is described. The composition comprises a butyl polymer (preferably a halogenated butyl polymer) and a styrene monomer. The styrene monomer is a copolymer of ?-methylstyrene and another styrenic monomerer (e.g., styrene and vinyl toluene). Relative to the base butyl polymer, the cold flow properties of the butyl polymer composition are improved along with a number of other properties.
