Abstract
Polymères et leurs moulages par rotation. On prévoit des compositions pour le moulage par rotation, comprenant un homopolymère ou un copolymère d'éthylène, une quantité réticulante d'un composé diperoxy acétylénique choisi dans le groupe se composant d'hexynes, d'octynes et d'octadiynes, et un pigment solide; ce pigment a un caractère et est en quantité pour fournir une surface spécifique ne dépassant pas 30 m**2/100 g de polymère, et le polymère a une teneur résiduelle en catalyseur à base de métal de transition inférieure à 3 parties par million. La présente invention est particulièrement utile pour fournir des compositions de polymères qui peuvent être moulées par rotation avec une formation minima de bulles.
