(27) ABSTRACT OF THE DISCLOSURE The invention relates to acid halide and/or acyllactam functional compounds, to polylactam block copolymers derived therefrom by lactam polymerization at a lactam group, and to the use of such block copolymers in polyamide mixtures. The compounds contain liquid crystalline compounds or compounds which combine with acyllactam to form a compound with liquid crystalline properties. The products of this invention are useful as accelerators in the preparation of nylon block copolymers, in particular block copolymers with improved stiffness. The block copolymers are useful in products requiring good tensile strength, chemical resistance and/or heat resistance, and are particularly useful in electrical engineering applications and in the aircraft industry.
