MANUFACTURING METHOD OF POLYCARBONATE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To manufacture a polycarbonate resin composition having excellent moldability and heat resistance. SOLUTION: A sulfonic acid compound is added to an aromatic carbonate obtained by polycondensing an aromatic dihydroxy compound with a diester carbonate in the presence of a specific catalyst to give an aromatic polycarbonate composition (A> having a rate of change of melt viscosity of 0.5% or less and a terminal hydroxyl group amount of 100 eq/ton or less. To 100 pts.wt. of the aromatic polycarbonate composition (A) are added 0.001-0.5 pt.wt. of a long chain fatty acid ester (B), of a 2-20C polyhydric alcohol, containing at least one bydroxyl group having formed an ester with an 8C or higher long chain fatty acid and 0.0001-0.01 pt.wt. of a compound (C) selected among inorganic acids and partial esters of inorganic acids.
