ABSTRACT:
Long fiber-reinforced normally solid polyamide resin compositions and molded articles formed thereof include a polyamide base resin, between 5 to 80% by weight of reinforcing fibers having a length of at least 3 mm, and between 0.01 to 3% by weight of a processing aid. The processing aid is a lithium salt of a fatty acid or a metal salt of a fatty acid having 22 to 32 carbon atoms. The compositions are preferably in the form of a generally cylindrical pellet having a length of 3 to 50 mm such that the reinforcing fibers are substantially as long as the pellet in which they are incorporated, and are oriented parallel to one another along the longitudinal axis of the pellet.
