Abstract
A rubber composition is based on at least one predominant vinylaromatic diene elastomer, having a vinylaromatic content of less than 10%; from 3 to 50 phr of a thermoplastic resin, denoted PPE resin, comprising optionally substituted polyphenylene ether units, the resin having a number-average molecular weight (Mn) of less than 6000 g/mol; from 5 to 60 phr of silica as predominant reinforcing filler; and a crosslinking system. Also disclosed are rubber articles comprising such a composition and in particular tires.
