PURPOSE: To obtain a polymer compsn. having excellent oil and weather resistance, comprising a specified wt. ratio of an α,β-unsatd. nitrile-conjugated diene copolymer, an ethylene α-olefin copolymer and a specific modified olefin copolymer. n CONSTITUTION: An α,β-unsatd. nitrile-conjugated diene copolymer (A) e.g.: acrylonitrile-butadiene copolymer), an ethylene-α-olefin copolymer (B) and a modified olefin copolymer (C) prepd. by adding 0.01W20pts.wt. monomer having an amino, hydroxyl, epoxy, carboxyl or acid anhydride group (e.g., maleic anhydride) to 100pts.wt. component B are mixed in such a ratio that the wt. ratio of component A to components B and C is 90:10W10:90 and the wt. ratio of component B to component C is 95:5W5:95 to obtain the titled compsn. being suitable as rubber material, etc., for automotive application. n COPYRIGHT: (C)1987,JPO&Japio |
