Abstract

Particules préexpansées d'une résine à base de polypropylène, obtenues par l'expansion de particules brutes de la résine à base de propylène, caractérisées en ce que la relation G1 - G2 > 10% existe entre la teneur G1 (%) de matière qui est contenue dans les particules préexpansées et est insoluble dans le n-heptane bouillant, et la teneur G2(%) de la matière contenue dans les particules brutes et qui est insoluble dans le n-heptane bouillant.
