ABSTRACT:
A lubricated aromatic polyester copolymer composition comprises an aromatic polyester copolymer of a mixture of terephthalic acid and isophthalic acid or derivative thereof at a molar ratio of terephthalic acid group to isophthalic acid group of 9:1 to 1:9 and a bisphenol having the formula ##STR1## wherein --X-- represents --O--, --S--, --SO.sub.2 --, --CO--, or either of an alkylene group or an alkylidene group which can be substituted by a hydrocarbon group having one or more carbon atom or a halogen atom or a halohydrocarbon group; and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.1 ', R.sub.2 ', R.sub.3 ', and R.sub.4 ' respectively represent hydrogen atom, a halogen atom, hydroxyl group or a hydrocarbon group; and a specific lubricant comprising more than 70 wt. % of n-paraffin having carbon atoms of 16 to 40 at a ratio of 0.05 to 5 wt. % based on said polyester copolymer.
