Polyamide-rubber blended composition |
摘要 |
The present invention describes a polyamide-rubber blended composition having improved resistance to ozone, stress whitening and gasoline prepared by mixing together with heating the following components: (a) from 70 to 20 volume percent of a rubber composition consisting of: (i) 30 to 70 volume percent of an acrylonitrile-butadiene copolymer containing at least 0.7 weight percent of a carboxyl group in the polymer, and (ii) 70 to 30 volume percent of an epichlorohydrin rubber; (b) 30 to 80 volume percent of a polyamide resin; and (c) at least 0.1 parts by weight of a polyepoxy compound in terms of the weight of the epoxy group per 100 parts by weight of the rubber composition of component (a), components (a) and (b) blended together after which component (c) is added and the resulting mixture kneaded with heat to form the polyamide-rubber blended composition.
