PRODUCTION OF PERFLUOROALKYLSULFONATE, PRODUCTION OF FLAME-RETARDANT POLYCARBONATE AND MOLDING PRODUCT COMPRISING THE POLYCARBONATE

摘要

PROBLEM TO BE SOLVED: To obtain the subject sulfonate capable of providing a polycarbonate molding product having excellent flame retardance while maintaining transpar ency when used alone as a flame-retardant by neutralizing a perfluoro alkylsulfonic acid with a basic compound. ;SOLUTION: This sulfonate is obtained by neutralizing (A) a perfluoro alkylsulfonic acid with (B) a basic compound. Sodium hydroxide, sodium alcoholate, etc., are preferably used as the component B. An alkaline(earth)metal perfluoroalkylsulfonate, a quaternary ammonium perfluoroalkylsulfonate, etc., may be cited as the obtained perfluoroalkylsulfonate. A polycarbonate is mixed with 0.01-3 wt.% based on the polycarbonate of the sulfonate as a flame- retardant to give a flame-retardant polycarbonate and molding the resin to give the objective molding product.;COPYRIGHT: (C)2001,JPO
