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.

Abstract: The present invention relates to a process for the preparation of an asphalt mix composition, said process comprising: (1) providing an asphalt composition and heating said composition to a temperature in the range of from 110 to 200° C.; (2) providing a granular material and heating said material to a temperature in the range of from 110 to 240° C.; (3) providing one or more thermosetting reactive compounds; (4) adding the one or more thermosetting reactive compounds provided in (3) to the asphalt composition obtained in (1) and homogenizing the mixture for a duration in the range of from 2 to 180 s; (5) adding the mixture obtained in (4) to the granular material obtained in (2) and homogenizing the slurry for a duration in the range of from 5 to 180 s. Further, the present invention relates to an asphalt mix composition obtained or obtainable by said process and its use.

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.
