Abstract: Disclosed is a method of preparing a blended thermoplastic resin composition that includes combining a ground crosslinked rubber with a thermoplastic material and a compatibilizer, and the products formed thereby. The ground crosslinked rubber has an average particle size of about 80 mesh or smaller. The thermoplastic material can be a polyolefinic resin or a polyolefinic elastomer or olefinic vulcanizate elastomer. The ground crosslinked rubber is included in amounts of up to 70% by weight, based on the total weight of the blended thermoplastic composition.

Abstract: Disclosed is a method of preparing a thermoplastic resin composition that includes combining a ground crosslinked rubber with a thermoplastic resin and a compatibilizer based on a paraffinic oil to form a blend thermoplastic composition. The ground crosslinked rubber has an average particle size of about 80 mesh or smaller. The thermoplastic resin includes at least one polyolefinic resin. The ground crosslinked rubber is included in amounts of up to about 70% by weight, based on the weight of the blend thermoplastic composition.

Abstract: The present invention relates to electrostatic dissipative polymeric compositions comprising a polyether polyurethane which can be blended with one or more base polymers. In some applications, the polyurethane is useful without further blending. Further, the polyurethane blends can be blended with glass beads or glass fibers which have a synergist effect when combined with the electrostatic dissipative agent.

Abstract: The present invention relates to electrostatic dissipative polymeric compositions comprising an effective amount of a chain extended polymer and a matrix polymer or matrix polymer blend. The chain extended polymer of the subject invention has electrostatic dissipative properties and is formed from low molecular weight polyethers which are reacted with a chain extender to furnish a useful additive.

Abstract: The present invention relates to electrostatic dissipative impact modified polymeric compositions comprising an effective amount of a chain extended block copolymer, polyvinyl halide and no more than 10 weight parts of a polymeric impact modifier per 100 weight parts of polyvinyl chloride. The chain extended block copolymer is formed from reacting a di-functional polyether with a chain extender which is a condensate selected from the group consisting of polyundecanolactam, polydodecanolactam, poly(11-aminoundecanoic acid) and (12-aminododecanoic acid).

Abstract: A thermoplastic polyurethane is provided which has electrostatic dissipative properties. The thermoplastic polyurethane comprises the polymeric reaction product of an ethylene ether oligomer glycol intermediate co-reacted with a non-hindered diisocyanate and an extender glycol to produce the polyurethane polymer. The ethylene ether oligomer glycol intermediate comprises a polyethylene glycol. The oligomer glycol intermediate has an average molecular weight from about 500 to about 5,000.

Abstract: A hinged flexible article is provided which has rigid or semirigid substrate means with an insert of a hinge material which permits repeated flexing of the article about the hinge without failure. The substrate means has a hardness of at least about 35 Shore D as measured by ASTM test D-2240, while the hinge material has a hardness of from about 25 to about 60 Shore D as measured by ASTM test D-2240.

Abstract: A method of manufacturing an electrostatic dissipating material (and compositions derived therefrom), wherein the method relates to:heat mixing or blending a first, a second and a third component in two steps, whereby in the first step the second and third components are first heat mixed or blended together to provide an initial mixture, and in a second step the first component is heat mixed or blended with said initial mixture,the first component is a polyolefinic, urethane, condensation, vinylic or styrenic polymer, the second component is a oxirane copolymer, and the third component is a polymer additive.
