Abstract
A method of bonding various materials, such as foam materials, to thermoplastic resins using a silane composition is provided. The thermoplastic resin is doped with a silane by washing the thermoplastic resin in a silane solution and then evaporating the solution from the resin. The silane-doped thermoplastic resin is then melted and formed into a polymeric article. In one embodiment, a polyurethane foam can then be sprayed onto the polymeric article. As the foam forms on the surface of the article, it bonds with silane trapped within the thermoplastic resin. In one embodiment, the polymeric article can be formed through a rotational molding technique. Through the process of the present invention, many useful articles can be formed such as polymeric pallets, water craft devices, thermocoolers and the like.
