防炎ポリカーボネート成形組成物
Document Type and Number:
Japanese Patent JP4272153
Kind Code:
B2
Abstract:
A thermoplastic molding composition having good flame resistance, melt flowability, resistance to chemicals and creep is disclosed. The composition contains A) at least one member having weight average molecular weight (Mw) of 25,000 to 35,000 g/mol, selected from the group consisting of aromatic polycarbonate and polyestercarbonate B) ABS graft polymer produced by the mass polymerization process and characterized in (i) having a butadiene content of 8 to 15% in relation to the weight of the graft polymer, (ii) having an acrylic acid derivative content of 15 to 30% in relation to the total weight of the acrylic derivative and styrene monomer, and (iii) containing styrene monomer-acrylic acid derivative copolymer having a weight average molecular weight of 5.104 to 14.104 g/mol. The composition may further contain one or more of halogen-free phosphorus compounds, fluorinated polyolefin, a polymer containing acrylate monomer and an inorganic material in particulate form.
