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 polyurethane elastomeric composition includes the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate-reactive component includes a polydiene polyol present in the isocyanate-reactive component in an amount of greater than 0 and less than about 95 parts by weight based on 100 parts by weight of the isocyanate-reactive component. The polydiene polyol has an average hydroxy functionality of no greater than about 3 and a number average molecular weight of from about 1000 to less than about 2000 g/mol.
