Battery jar material for sealed secondary battery and battery jar for sealed secondary battery using the same
摘要：
A battery jar material for sealed secondary batteries comprising a resin composition which comprises 50 to 98% by weight of (A) a styrenic polymer having a syndiotactic configuration, 2 to 50% by weight of (B) at least one polymer selected from the group consisting of polyolefins and styrenic elastomers, and 0 to 10% by weight of (C) a polyphenylene ether, or a resin composition which comprises 100 parts by weight of a resin component having the same composition as the above resin composition, 1 to 350 parts by weight of (D) an inorganic filler, and 0 to 5 parts by weight of (E) a polyphenylene ether modified with a polar group; and a battery jar for sealed secondary batteries made of this material. A battery jar material and a battery jar for sealed secondary batteries which show excellent heat resistance, resistance to electrolytes, resistance to oil and grease, electric insulation, mechanical strengths, and moldability and enable decrease in thickness are provided.
