Abstract

Préparation de particules de résine du type du propylène, réticulées et prémousseuses, en utilisant comme résine de base un copolymère au hasard de propylène dont la quantité de chaleur de critallisation, déterminée par la méthode DSC,est de 19 à 10 cal./g. Les particules prémousseuses ont une fraction de gel de 1 à 65%. On apporte aussi un article moulé d'une résine réticulée, du type du propylène, qui est un agrégat fusionné des dites particules du type prémousseux, dans lequel le nombre de cellules, N par mm2, et la densité d(g/cm3), ont la relation représentée par l'expression 2<N1/2 / d1/3<45.
