    摘要: The present invention relates to a pressure sensitive adhesive foam with a percentage of theoretical density less than 90, wherein the foam has a peel adhesion of greater than about 1 N/cm and a compression set under constant deflection of less than about 60%. The present invention further includes a pressure sensitive adhesive foam comprising a thermoplastic block copolymer, a tackifying resin; an isocyanate terminated monomer or oligomer; a polymer comprising a backbone selected from the group consisting of polybutadiene, polyester and polyether, wherein the polymer contains at least 2 active hydrogens capable of reacting with the isocyanate terminated monomer; and expandable particulate materials. The present invention further includes a pressure sensitive adhesive foam comprising a thermoplastic olefin polymer or copolymer, having a density less than 0.91 g/cm3 and a torsion modulus less than 18 MPa, and a tackifying resin; and, optionally, plasticizing oil and expandable particulate materials, or glass microspheres. The invention finally further comprises a method of forming the above film.

    摘要: Skis of laminated construction are assembled by joining the several lamellae with a hot metal adhesive which preferably contains an effective amount of an adhesion promoting agent. The hot melt adhesive is preferably a linear polyester, polyesteretheramide, polyetherester, polyamide, polyetherurethane, copolymer of ethylene-vinylacetate, polyesteramide, or polytheramide, and when the adhesve is based on a copolymer, it is more preferable still that the copolymer is a block copolymer.

    摘要: Finished articles made of flexible polyvinyl chloride (PVC) using plastisol technology are improved in terms of resistance to heat and solvents and reduction in plasticizer migration by incorporating into the traditional plastisol ingredients substantial amounts of blocked di- or polyisocyanates and di- or polyols and/or di- or polyamines, which, upon heating react with each other to form a polymer network within the article while the PVC is gelling.
