    摘要: In one embodiment, this invention provides a composition comprising a functionalized block copolymer crosslinked with acetylacetonate. The crosslinked block copolymer has improved solvent resistance and improved cohesive strength at high temperatures. The crosslinked block copolymer comprises preferably an acid functionalized, hydrogenated block copolymer having an ABA or similar structure wherein the block comprises at least 80 wt % of a vinyl-aromatic hydrocarbon, preferably styrene, and wherein the B block comprises at least 80 wt % of a hydrogenated and conjugated diene, preferably butadiene, isoprene or a mixture thereof. In another embodiment, this invention provides an adhesive, sealant, oil gel, asphalt composition, or wax composition comprising the acid functionalized, hydrogenated block copolymer.

    摘要: The invention herein relates to polyurethane coating and adhesive compositions containing partially unsaturated monohydroxylated polydiene polymers which are comprised of at least two polymerizable ethylenically unsaturated monomers wherein at least one is a diene monomer which yields unsaturation suitable for epoxidation. The invention preferably encompasses the use of epoxidized derivatives of these novel partially unsaturated monohydroxylated polydiene polymers and epoxidized derivatives of unsaturated monohydroxylated polydiene polymers in such mating and adhesive compositions. The preferred monohydroxylated polydiene polymer of the present invention has a structural formula:(HO).sub.x -A-S.sub.z -B-(OH).sub.y (I)wherein A and B are polymer blocks which may be homopolymer blocks of conjugated diolefin monomers, copolymer blocks of conjugated diolefin monomers, or copolymer blocks of diolefin monomers and monoalkenyl aromatic hydrocarbon monomers. The A blocks have a molecular weight of from 100 to 6000, preferably 100 to 3,000, and most preferably 500 to 2000, and the B blocks have a molecular weight of from 1000 to 15,000, preferably 3000 to 7000, and most preferably 2000 to 6000. S is a vinyl aromatic hydrocarbon block which may have a molecular weight of from 500 to 10,000. x and y are 0 or 1 and either x or y must be 1 but only one at a time can be 1. z is 0 or 1. These polymers are preferably epoxidized such that they contain from 0.5 to 7.0 milliequivalents (meq) of epoxy per gram of polymer.
