Abstract:
A process of producing reinforced laminates from crosslinkable thermoplastic olefin polymer material. In the process, a normally solid, high molecular weight crosslinkable thermoplastic olefin polymer containing a catalyst which reacts with and effects crosslinking of the polymer and which has a decomposition temperature above the melting temperature of the polymer, is heated to a molten state at a temperature above the polymer melting temperature but below the catalyst decomposition temperature. A continuous nonreinforced sheet is then formed from the molten polymer at a temperature below the decomposition temperature and is applied to at least one surface of a substrate to form a laminate. The laminate is then heated under pressure to a temperature above the decomposition temperature of the catalyst to effect substantially complete crosslinking of the polymer and is cooled to a temperature below the polymer melting temperature to a self-supporting state to fix the shape of the laminate.
