Zusammenfassung:	PURPOSE:The titled compsn. excellent in stability of mechanical and electrical characteristics to retention and heat, comprising an arom. polyester, a specified cyanuric acid ester compd., Sb2O3 and a sulfide compd. CONSTITUTION:100pts.wt. arom. polyester of relative viscosity of 1.15-2.0 (in 0.5% o-chlorophenol soln. at 25 deg.C) such as polyethylene terephthalate, 3-50pts. wt. cyanuric acid ester of halogenated bisphenol of the formula I [wherein Ar is a monovalent arom. group which may be substd. with halogen or a (halogenated) lower alkyl; Ar is a halogen-substd. divalent arom. group; n is 1-50], 1-20pts.wt. Sb2O3, 0.01-3pts.wt. sulfide compd. of the formula II [R is 3- 30C alkyl; Al is 1-10C (substd.) alkylene] and, if necessary, 0.1-10pts.wt. polyepoxy compd. are molten and kneaded.
