ELECTRIC/ELECTRONIC PART COMPOSED OF AROMATIC POLYCARBONATE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain an electric/electronic prat composed of an aromatic polycarbonate resin composition comprising a polymer obtained from a biomass resource and having excellent heat resistance, mechanical properties and durability stability. SOLUTION: The electric/electronic part is composed of an aromatic polycarbonate resin composition which comprises (A) 100 pts.wt. of an aromatic polycarbonate resin (component A) and (B) 1-200 pts.wt. of a polylactic acid (component B). The polylactic acid (component B) comprises (B-1) a polylactic acid unit (component B-1) consisting of 90-100 mol% of an L-lactic acid unit and/or 0-10 mol% of a D-lactic acid unit and/or a copolymerization component unit except lactic acid and (B-4) a polylactic acid unit (component B-4) consisting of 90-100 mol% of a D-lactic acid unit and 0-10 mol% of an L-lactic acid unit and/or a copolymerization component unit except lactic acid in the weight ratio (component B-1/component B-4) of the component B-1 and the component B-4 of 10/90 to 90/10.
