CONSTITUTION:The following three components A-C are melt-kneaded together. (A): 5-50pts.wt. polyamide of a m.p. >=170 deg.C; (B): 95-50pts.wt. nitrile rubber; and (C): an organic peroxide having a 1min half-life temperature >=185 deg.C in an amount to provide 0.002-0.05mol of the peroxide group per 100g of the nitrile rubber (B) are melt-kneaded together (the total of A and B being 100pts. wt.). As component A, nylon 11, nylon 12, nylon 6/60 or nylon 6/66/610 is desirable. Examples of component C include di-t-butyl peroxide and 2,5-dimethyl-2,5- di-t-butylperoxyhexyne-3.

    Abstract: PURPOSE:To obtain a composition of good appearance with high performance in flexibility, low-temperature characteristics resiliency and bleedout resistance, by incorporating a polyether-esteramide with a vinyl chloride graft copolymer. CONSTITUTION:The objective composition can be obtained by incorporating (A) 1-99wt% of a polyether esteramide derived from (i) a >=6C aminocarboxylic acid or (ii) a >=6C lactam or (iii) a salt from >=6C diamine and dicarboxylic acid and (iv) a poly (alkylene oxide) glycol with a number-average molecular weight 300-6,000 and (v) a 4-20C dicarblxylic acid with (B) 99-1wt% of a vinyl chloride graft copolymer prepared by graft copolymerization of vinyl chloride to ethylene-vinyl acetate copolymer. The EVA of the component B is preferably with such amount of the vinyl acetate copolymerized as to fall between 10 and 90wt%. The component B is preferably with such amounts the EVA and vinyl chloride copolymerized falling between 30 and 70wt% and 70 and 30wt%, respectively.
