ABSTRACT:
Novel aromatic nitrile-containing polyester, polyamide, and silicone polymers are described. These nitrile-containing polymers are heat resistant and are used as fibers and resins and to prepare fiber-reinforced composites exhibiting outstanding mechanical strength at room and particularly elevated temperatures. Styrene-butadiene and styrene-acrylonitrile copolymers are described wherein at least some of the phenyl groups contain nitrile substituents. Composites having various shapes such as tires are described utilizing these nitrile-containing copolymers reinforced with fibers either containing aromatic nitrile groups or coated with resins containing nitrile substituted aromatic groups. These composites are useful in a variety of applications. The procedure for preparing such composites is disclosed.
