Abstract

L'invention concerne un procédé relatif à l'élaboration de mélanges très uniformes obtenus par voie fondue, d'homopolymères de nylon semi-cristallins et de copolymères de nylon semi-cristallins. Lesdits mélanges ont un point de fusion significatif unique qui remplace les points de fusion individuels propres aux différents constituants de nylon. Selon une variante, l'écart entre la température de fusion du mélange et sa température de cristallisation est supérieur à l'écart entre ces deux températures pour chacun des homopolymères et copolymères constitutifs susmentionnés. Selon une autre variante, le mélange a une température de fusion à peu près équivalente à celle de l'homopolymère de nylon semi-cristallin.
