Abstract: A curable composition comprises 0.1 to 50 weight percent of a curable epoxy resin, the weight percent being based on the total resin composition, an effective mount of a curative for the curable epoxy resin, 50 to 99.9 weight percent of at least one of a fully prepolymerized hydrocarbon polyolefin resin and a fully prepolymerized functionalized polyolefin resin, the weight percent being based on the total resin composition, wherein said hydrocarbon polyolefin is present in the range of 25 to 99.9 weight percent of the total resin composition and said functionalized polyolefin is present in the range of 0 to 49.9 weight percent of the total resin composition, said composition being free of epoxidized natural and/or synthetic rubber.

Abstract: The present invention relates to an article comprising a substrate which has coated thereon a photopolymerizable epoxy composition containing a plurality of epoxides including at least one selected from the group consisting of bisphenol A epoxides and cycloaliphatic epoxides, and at least one aliphatic epoxide, from about 0.1% to about 2% of at least one organometallic cationic initiator capable of initiating polymerization at wavelengths of from about 200 to about 600 nm, and optionally at least one accelerating agent. The article can be a flexible tape backing or a chip-resistant paint.

Abstract: A stabilized heat curable adhesive prepared from a formulation comprised of (1) at least one free radically polymerizable monomer; (2) at least one epoxy function monomer; (3) at least one free radical polymerization photoinitiator; (4) a thermally-initiated cationic catalyst system comprising (a) at least one salt of an organometallic cation, (b) at least one stabilizing additive; (5) optionally, at least one alcohol-containing material; and (6) optionally, adjuvants.

Abstract: A method for preparing an oriented microporous shaped article is provided. The method comprises the steps of melt blending thermoplastic polymer with a solubilizing amount of a compatible liquid to form a homogeneous solution, forming a shaped article from the solution, cooling the shaped article at a rate and to a temperature sufficient to initiate thermodynamic, non-equilibrium liquid-liquid phase separation and then to solidify the thermoplastic polymer, stretching the article in a first direction sufficient to permanently attenuate the article and effect orientation of the polymer, and removing at least a substantial portion of the compatible liquid before or after the stretching step to form an oriented microporous shaped article.

Abstract: A microporous particulate-filled thermoplastic polymeric article is provided. The article can be in the form of a film, a fiber, or a tube. The article has a thermoplastic polymeric structure having a plurality of interconnected passageways to provide a network of communicating pores. The microporous structure contains discrete submicron or low micron-sized particulate filler, the particulate filler being substantially non-agglomerated.
