Abstract
PURPOSE: The title composition usable for mechanical and electrical parts, having improved heat resistance and color stability, particularyly at high temperatures, without promoting the thermal decomposition of the composition, comprising a phosphite and a specific aromatic polyester.
CONSTITUTION: A composition comprising (A) 100 parts by wt. of an aromatic polyester having a melting point of 150W350°C, a molecular weight of 5,000W 50,000, an intrinisic viscosity of 0.4W1.5 measured by using a 0.5% solution in 0-chlorophenol at 25°C, containing a phenol derivative of formula I or II: (R' is H, 1W16C alkyl, or halogen; n is 1 or 2; m is integer 0W2; A is 1W6C alkylene, ether, carboryl, thioether, or sulfone group), and (B) 0.01W5 parts by wt., prefreably 0.05W0.5 part by wt., of at least one type of phosphite of formaula III or a IV: (R is 6W20C alkyl group). The additionn of 0.01W5 parts wt of an epoxy compound further improves the effect of the present invention.
