<p>PURPOSE:To improve the strength, toughness, dimensional accuracy and stability, workability, and electrical characteristics of a post base material by using a polyarylene sulfide resin having specific characteristics as the post base material. CONSTITUTION:The post base material 1 is formed of the resin molding which consists basically of polyarylene sulfide and has 1X10<1>-1X10<10>OMEGA surface resistivity. The polyarylene sulfide resin to be used as the base resin refers to the polymer having >=90mol.% repeating unit expressed by the constitutional formula -(Ar-S)- (where Ar is an aryl group). The resin molding which consists basically of such polyarylene sulfide resin, is compounded with an electrical conductivity imparting agent or antistatic agent and has 1X10<1>-1X10<10>OMEGA measured surface resistivity is used. The strength, toughness, electrical characteristics, workability, dimensional accuracy, and dimensional stability are thereby improved.</p> |
