MOLDED TUBULAR ARTICLE OIL-RESISTANT AT HIGH TEMPERATURE AND COVER BOOT

摘要

PURPOSE:To prepare a molded tubular article excellent in oil resistance at high temp. and in flexibility by molding a compsn. contg. a specific polyester and a polycarbodiimide into a tube. CONSTITUTION:A molded tubular article is prepd. by molding a compsn. prepd. by compounding 0.3-5.0 pts.wt. polycarbodiimide into 100 pts.wt. polyester which is prepd. from an aliph. dicarboxylic acid of formula I, an aliph. diol, a dihydroxy compd. of formula II, and at least one monohydroxy compd. of formula III, contains 2-10mol.% units derived from the dihydroxy compd. and/or the monohydroxy compd., and has an intrinsic viscosity at 30 deg. in o-chlorophenol of 0.8-3.0.
