Abstract

Particules multicouches comportant un noyau et une enveloppe, utilisées pour fabriquer des articles par rotomoulage. Le noyau et l'enveloppe peuvent être constitués de polymères thermoplastiques. La différence d'indice de fusion entre le noyau et l'enveloppe est d'au moins 0,5 unités d'indice de fusion, la différence de T¿f? entre le noyau et l'enveloppe étant éventuellement d'au moins 1 ~C. Les particules dont se composent le noyau et l'enveloppe servent à fabriquer par rotomoulage un article comportant généralement une couche extérieure qui fond plus facilement et une couche intérieure, plus dure.
