    Abstract: A composite article includes a low surface energy polymer layer, a poly(meth)acrylate layer, an epoxide layer, and a hydrolytically resistant layer. The poly(meth)acrylate layer is disposed on and in direct contact with the low surface energy polymer layer and includes the reaction product of at least one acrylate that is polymerized in the presence of an organoborane initiator, such that the poly(meth)acrylate includes boron. The epoxide layer is disposed on and in direct contact with the poly(meth)acrylate layer. The hydrolytically resistant layer is disposed on and in direct contact with the epoxide and is the reaction product of an isocyanate component and an isocyanate-reactive component reacted in the presence of a curing agent. The isocyanate-reactive component includes a polydiene polyol and the curing agent crosslinks the carbon-carbon double bonds of the polydiene polyol.

    Abstract: A process for producing a polyurethane shoe sole having an article density of 100 to 350 g/L and being made from an organic polyisocyanate, a polyol, a blowing agent consisting of water, and optionally a crosslinking and/or chain-extending agent, a catalyst, and other auxiliaries and/or additives. First, polyisocyanate, polyol and any crosslinking and/or chain-extending agent are mixed and reacted at a temperature of 110° C. to 180° C. to give a prepolymer having polyisocyanate groups. Second, the isocyanate-terminated prepolymer obtained and any remaining polyisocyanate are mixed with any remaining polyol, blowing agent comprising water, and any remaining crosslinking and/or chain-extending agent and also any catalyst and other auxiliaries and/or additives are introduced into a mold and allowed to fully react to give a polyurethane shoe sole.

    Abstract: A process for producing a polyurethane-coated conduit element includes mixing a) a mixture of aromatic and aliphatic polyisocyanate with, b) at least one polymeric compound having at least two hydrogen atoms which are reactive toward isocyanate, c) at least one chain extender, d) a catalyst, and e) optionally at least one other auxiliary, additive, or both, to form a reaction mixture; applying the reaction mixture to a conduit element; and allowing the reaction mixture to react to form a polyurethane layer. The polyurethane-coating conduit element is suitable for maritime applications in the oil and gas industry, which polyurethane has improved hydrolysis stability at high temperatures and nevertheless satisfies the high mechanical demands in the oil and gas industry.
