Polycarbonate-polydiorganosiloxane copolymer, its resin composition, and its production method |
| abstract |
PROBLEM TO BE SOLVED: To provide a polycarbonate-polydiorganosiloxane copolymer or a resin composition thereof having both excellent impact resistance, particularly impact resistance at an extremely low temperature and chemical resistance, and a method for producing the same. Is to provide. A copolymer or a resin composition thereof of the present invention is the copolymer or a resin composition thereof containing a polycarbonate-polydiorganosiloxane copolymer and an optional polycarbonate resin. The copolymer comprises (A-1) polycarbonate block and (A-2) polydiorganosiloxane block. The (A-2) polydiorganosiloxane block is contained in the copolymer or its resin composition in an amount of 2.5 to 8.0% by weight, and the following (i) and (ii) are contained. The copolymer or resin composition thereof to be satisfied: (I) In a cross-sectional observation image of the copolymer or its resin composition using an electron beam microscope, 1 to 20 domains having a maximum major axis of 80 nm or more are present in a region of 850 nm square (722,500 nm 2). And (ii) the average domain size is 30-100 nm. [Selection diagram] None |
