RESIN COMPOSITION AND CONNECTOR FOR OPTICAL COMMUNICATION MOLDED THEREFROM

摘要

PURPOSE:To provide a resin compsn. which gives connectors for optical communication with good productivity, which has excellent dimensional stability, by blending carbon black and a phosphite compd. with an arom. polyester. CONSTITUTION:0.01-1pt.wt. carbon black (pref. channel carbon black whose surface acidity is a pH of 4-6), 0.01-5pts.wt. phosphite compd. (e.g. tridecyl phosphite), 0-10pts.wt. titanium oxide and 0-10pts.wt. metal salt of an org. acid (e.g. zinc stearate) are blended with 100pts.wt. arom. polyester having an intrinsic viscosity of 0.7dl/g at 32 deg.C in chloroform, composed of an arom. dicarboxylic acid and a dihydric phenol compd.
