Abstract

Elastomers opt. contg. non-conjugated diene are made high-temp. oxidn. resistant, by incorporating >=0.2 pts. wt. boric acid per 100 pts. wt. copolymer. The compsn. also contains a hindered phenolic antioxidant and/or an aromatic amine antioxidant and/or a chlorinated polymer e.g. polychloroprene or PVC.
