Title (EN) IN SITU ISOMERIZATION OF POLYBUTADIENE
(FR) ISOMÉRISATION IN SITU DE POLYBUTADIÈNE
Abstract:
(EN) Particular embodiments of the present invention include rubber articles manufactured at least in part from a rubber composition that is based upon a cross -linkable rubber composition, the cross-linkable rubber composition comprising, per 100 part by weight of rubber (phr), at least 10 phr of a polybutadiene rubber and up to 90 phr of a second rubber component having at least some dienic unsaturation. The polybutadiene has a cis- 1,4 content of at least 80 wt%. A disulfide isomerization agent, which in particular embodiments may be a vulcanization agent, is included in the rubber composition at an amount of at least 3 phr. However such agents do not include disulfides that are thiurams.
(FR) Des modes de réalisation particuliers de la présente invention comprennent des articles en caoutchouc fabriqués au moins en partie à partir d'une composition de caoutchouc qui est basée sur une composition de caoutchouc réticulable, la composition de caoutchouc réticulable comprenant, pour 100 parties en poids de caoutchouc (pcc), au moins 10 pcc d'un caoutchouc de polybutadiène et jusqu'à 90 pcc d'un second constituant caoutchouc ayant au moins une certaine insaturation diénique. Le polybutadiène a une teneur en cis-1,4 d'au moins 80 % en poids. Un agent d'isomérisation disulfure, qui dans des modes de réalisation particuliers peut être un agent de vulcanisation, est inclus dans la composition de caoutchouc à hauteur d'au moins 3 pcc. Cependant de tels agents ne comprennent pas de disulfures qui sont des thiurames.
