PURPOSE:To obtain a polyester composition having antistatic properties and excellent dispersity and heat resistance of antistatic agent by mixing metallic salt of organic sulfonic acid as antistatic agent into polyester copolymerized with dicarboxylic acid having metallic base of sulfonic acid. CONSTITUTION:(A) 100 pts.wt. copolymerized polyester having acid component in which >=70mol%, preferably >=80mol% is terephthalic acid and 0.05-10mol%, preferably 0.05-7mol% is dicarboxylic acid having metallic base of sulfonic acid (preferably 5-sodium sulfoisophthalate) is mixed with (B) 0.05-10 pts.wt., preferably 0.1-3 pts.wt. metallic salt of organic sulfonic acid expressed by the formula [R is >=6C alkyl, aryl or alkylaryl; M is alkali (earth) metal; n is 1 or 2] (preferably sodium salt of dodecylbenzene sulfonic acid), preferably before ester interchange or esterification and polycondensation of the component A. |
