Abstract
Self-reinforced polymer composites of about 98-2% by weight of a mixture of polystyrene and poly(phenylene oxide) and about 2%-98% by weight of a melt processable wholly aromatic polyester which exhibit anisotropic properties in the melt phase. This wholly aromatic polyester is a liquid crystal polymer, or LCP. The composite contains predominantly unidirectionally oriented fibers primarily in the range of about 1 to 10 micrometers in diameter formed in situ, from the wholly aromatic polyester, distributed in a polymer matrix of the mixture. The polymer composites of this invention have high tensile strength, high modulus, satisfactory elongation, good impact strength, and good high temperature properties, especially at LCP amounts of 40% by weight and upwards.
