Abstract (en)

[origin: WO9946334A1] A method for forming extremely uniform, melt blended mixtures of semi-crystalline nylon homopolymers with semi-crystalline nylon copolymers. The blends have a single significant melting point rather than maintaining the melting points of the individual nylon component parts. In one embodiment, the blend has a larger difference between its melting temperature and its crystallization temperature than each of the semi-crystalline nylon homopolymer and semi-crystalline nylon copolymer components. In another embodiment, the blend has a melting temperature that is about equal to that of the semi-crystalline nylon homopolymer.
