Document Type and Number:
Japanese Patent JP2022124789
Kind Code:
A
Abstract:
To provide a resin composition which is excellent in permeability, surface hardness, heat resistance and rigidity.SOLUTION: A polycarbonate resin composition comprises 99.9 to 50 pts.wt. of (A) a polycarbonate resin (component A), and 0.1-50 pts.wt. of (B) a copolymer (component B) which comprises 6-47 mol% of a constitutional unit (b-1) derived from an aromatic (meth)acrylate monomer, 47-93 mol% of a constitutional unit (b-2) derived from an alkyl (meth)acrylate monomer and 1-30 mol% of a constitutional unit (b-3) derived from a modified aromatic vinyl monomer, and has a weight average molecular weight of 5,000-30,000, wherein the component A contains a polycarbonate copolymer (A-1 component) which is constituted of a constitutional unit (a-1) represented by the following formula (1), a constitutional unit (a-2) represented by the following formula (2) and a constitutional unit (a-3) represented by the following formula (3), in which a ratio of the constitutional unit a-1 in the whole constitutional units is 5-15 mol%; a ratio of the constitutional unit a-2 is 20-60 mol%; and a ratio of the constitutional unit a-3 is 25-75 mol%.SELECTED DRAWING: None
