ABSTRACT:
A self-reinforced polymer composite in the form of a non-laminated shaped article is prepared by (a) melt blending (I) a matrix polymer which is a melt processable flexible chain polymer or first liquid crystal polymer (LCP) and (2) a fiber forming melt processable second LCP under high strain mixing conditions inducing fiber formation, cooling and stretching the resulting blend, and (b) shaping the resulting blend by injection molding or extrusion at a temperature which is above the minimum melt processing temperature of the matrix polymer but below that of the fiber forming second LCP. By shaping at a temperature below the minimum processing temperature of the fiber-forming LCP, the fiber structure formed during cooling is preserved. The resulting shaped articles have outstanding mechanical properties, e./g., tensile strength, modulus and impact strength.
