(JP9180689-A)      A battery jar material for sealed secondary battery comprises a resin composition containing 50-98 wt.% syndiotactic styrene polymer (A), 2-50 wt.% at least one selected from polyolefin and styrene elastomer (B) and 0-10 wt.% polyphenylene ether (C).    Also claimed is another battery jar material comprising 100 pts. wt. a resin component composed of 5-98 wt.% (A), 2-50 wt.% (B) and 0-10 wt.% (C), 1-350 pts. wt. an inorganic filler (D) and 0-5 pts. wt. polyphenylene ether modified with a polar group.    USE -   The battery jar material obtained from the resin composition may be used in making battery jar for sealed secondary battery (claimed), for employment in electric vehicle particularly battery-operated fork-lift.    ADVANTAGE -   The material is lightweight, high resistance to heat, electrolyte and oil/grease, and has high electrical insulation, mechanical strength and mouldability, as well as capability to form thinner walls. When used, it does not deformation due to the generated heat and rise in internal pressure during rapid charging up of the battery, and is also suitable for operation at high temperatures, e.g. in electric vehicle for use outdoor at temperature of 100C.
