Abstract

Official abstract text for this publication.

The present invention relates to a rubber composition based on at least an epoxidized natural rubber (ENR), a reinforcing filler and, as plasticizing agent, an alpha-methylstyrene polymer resin. The invention also relates to the use of such a composition for the manufacture of a tire tread exhibiting an improved compromise of properties with respect to grip on wet ground and rolling resistance.

First claim

Opening claim text (preview).

The invention claimed is: 1. A rubber composition based on at least an epoxidized natural rubber (abbreviated to “ENR”), a reinforcing filler and, as plasticizing agent, an alpha-methylstyrene polymer resin having a number-average molecular weight between 400 and 2000 g/mol, a polydispersity index of less than 3, and a T g of greater than 20° C., which is miscible in the rubber composition at the content of resin and ENR present therein, and which is selected from the group consis…
