<p>A vulcanisable rubber compsn. comprising per 100 pbw rubber, 2-10 pbw CdO 2-20 pbw MgO, 1-8 pbw cadmiumdialkyldithiocarbamate and 0.5-7 pbw aromatic amine e.g. acetyl diphenylamine. The rubber is pref. butadiene-acrylonitrile copolymer (10-50 wt. % acrylonitrile) on a styrene-butadiene rubber (at least 50% wt. butadiene). The rubber composition has improved heat stability.</p> |
