Title (EN) THERMOPLASTIC VULCANIZATES
(FR) VULCANISATS THERMOPLASTIQUES
Abstract:
(EN) A process for preparing a thermoplastic vulcanizate, the process comprising: charging a reactor with an olefmic copolymer rubber, where the olefmic copolymer rubber is characterized by a multimodal molecular weight, an average branching index of greater than 0.8, includes less than 10 parts by weight oil per 100 parts by weight rubber, includes less than 1 parts by weight non-rubber particulate, per 100 parts by weight rubber, and is in the form of granules having a particle size less than 8 mm; charging the reactor, contemporaneously or sequentially with respect to the rubber, with a thermoplastic resin, an oil, and a cure system; melt mixing the rubber, the thermoplastic resin, the oil, and the cure system; and dynamically vulcanizing the rubber.
(FR) Cette invention concerne un procédé de préparation d'un vulcanisat thermoplastique, ledit procédé comprenant les étapes consistant à : charger un réacteur avec un caoutchouc du type copolymère oléfinique, ledit caoutchouc du type copolymère oléfinique étant caractérisé par un poids moléculaire multimodal, un indice de ramification moyen supérieur à 0,8, et en ce qu'il contient moins de 10 parties en poids d'huile pour 100 parties en poids de caoutchouc, moins de 1 partie en poids de fractions particulaires non-caoutchouc pour 100 parties en poids de caoutchouc, et en ce qu'il est sous la forme de granules ayant une taille de particules inférieure à 8 mm ; charger le réacteur, simultanément ou séquentiellement par rapport au caoutchouc, avec une résine thermoplastique, une huile et un système de durcissage ; mélanger à chaud le caoutchouc, la résine thermoplastique, l'huile et le système de durcissage ; et vulcaniser dynamiquement le caoutchouc.
