DIENE ELASTOMER MODIFIED, SYNTHESIS METHOD FOR SAME AND RUBBER COMPOSITION COMPRISING IT |
摘要 |
A modified diene elastomer comprises: at least 55% by weight of entity coupled by a functional group bearing a function of formula —SiOR, in which R is a hydrogen atom or an alkyl radical, and optionally bearing another function capable of interacting with a reinforcing filler, from 5% by weight to 30% by weight of star-branched entity having three elastomeric branches connected to one and the same silicon atom belonging to a functional group bearing or not bearing a function capable of interacting with a reinforcing filler, less than or equal to 15% by weight of entity functionalized at the chain end by a functional group bearing a function —Si(OR)2, in which R is a hydrogen atom or an alkyl radical, and optionally bearing another function capable of interacting with a reinforcing filler, and a content of less than or equal to 15% by weight of non-functional diene elastomer. |
