Abstract: A low molecular weight engineering thermoplastic polyurethane (ETPU) can be homogeneously melt blended with a polyarylene ether (PAE) to give a low viscosity melt processable blend, and subsequently cooled to form a heterogeneous dispersion of the ETPU in the PAE that has two Tgs, one that is close to the Tg of the pure ETPU, and one that is close to the Tg of the pure PAE. As such, the composite blend retains the properties of the polyarylene ether.

Abstract: A fiber-reinforced depolymerizable and repolymerizable thermoplastic composite that is encased in a depolymerizable and repolymerizable thermoplastic resin exhibits the strength and stiffness that make the encased composite particularly suitable for a wide array of applications that require very high strength, stiffness, and exceptional impact, together with complex shape. Examples of such applications include bumper beams, pedals, car door structures, instrument panels, and seating structures for automotive use. Other applications include window profiles, skis, ski poles, mast stays, tent poles, concrete reinforcement, crash barriers, window or door lineals, cable trays, cable for optical fibers, bicycle wheels and frames, and pipe.

Abstract: Fiber-reinforced composites prepared from a depolymerizable and repolymerizable polymer have the processing advantages of a thermoset without being brittle. Impregnation of polymer into the fiber bundle can be achieved with ease, while still producing a composite with excellent physical properties and high damage tolerance.

Abstract: The present invention is a laminated glazing comprising a rigid thermoplastic polyurethane sheet or film sandwiched between and adhering to an outer glass sheet and an inner glass sheet. This glazing can be made to be sufficiently thin to make it particularly suitable for intrusion-resistant automotive applications.

Abstract: A blend of a polyarylene ether and a dispersible reactive solvent such as a thermoplastic polyurethane or a cyclopentadiene can be processed at temperatures below the oxidative degradation temperature of the polyarylene ether, yet form an article upon cooling that substantially retains the properties of the polyarylene ether.
