    摘要: A multilayer polymeric composite structure of high impact strength and delamination resistance possesses a polymeric cosmetic layer chemically bonded to a cross-linked, isocyanate-modified thermosetting polyester or polyether substrate layer. In one embodiment of the structure, a relatively thin, predominantly acrylic resin layer is chemically bonded through urethane linkages to a relatively thick, reinforced, polyester foam substrate layer. The composite structure can be fabricated into light weight, durable articles, i.e., plumbing fixtures which include bathtubs, sinks, shower receptors and the like. A reinforced reaction injection molding (RRIM) procedure for manufacturing the polymeric composite structure is also disclosed.
