Abstract

La invención se relaciona con una partícula de polvo de poliamida (PA) 5sembrada constituida por una corteza en PA6 o PA6/12 y por un núcleo PA6, PA11, PA12, PA6/12, PA6.12, PA6.6, PA( o PA4, siendo el núcleo y a corteza bien de naturaleza en poliamida idéntica pero de masa molecular diferente, bien sea de naturaleza de poliamida diferente. La partícula cuya corteza tiene una temperatura de fusión Tf1 y una temperatura de cristalización Tc1 y cuyo núcleo 10 tiene una temperatura de fusión Tf2 y una temperatura de cristalización Tc2 se caracteriza porque la diferencia en valor absoluto entre Tf1-Tc1 y/o entre Tf2-Tc2 es superior a la diferencia en valor absoluto entre la temperatura de fusión y la temperatura de cristalización de una partícula de polvo sembrada por una carga mineral y cuya corteza es en PA6, 15 PA12 o PA6/12.
