Abstract
1491030 Elastomer composition EXXON RESEARCH & ENG CO 31 Dec 1974 [21 Feb 1974] 56141/74 Heading C3P and C3Q An elastomer blend (for use in tyre flexing components of improved flex, ozone resistance and weather resistance) comprises a mixture of: (a) a rubber blend comprising 50-60% by weight of natural rubber, the balance being styrene-butadiene rubber; and (b) a chlorinated ethylene-propylene-diene terpolymer (EPDM) in an amount of 25-43 parts per 100 by weight of rubber blend (a), the chlorinated-EPDM comprising 0.1-4% by weight of chlorine. The chlorinated EPDM is preferably derived from an EPDM comprising 48 wt. per cent ethylene, 43 wt. per cent propylene and 9 wt. per cent ethylene norbornene. The chlorinated EPDM may be prepared by either : (a) dissolving the EPDM in n-heptane at 80‹ C., adding N- chlorosuccinimide and benzoyl peroxide and stirring for 4-33 hours, removing insoluble products, and the polymer precipitated by adding the solution to acetone; or by (b) blending the EPDM and 1,3-dichloro-5,5-dimethylhydrantoin (optionally with benzoyl peroxide), and heating, e.g. at 320‹ F. for 20 minutes.
