TERMINAL MODIFIED POLYCARBONATE AND MANUFACTURING PROCESS THEREOF
摘要:
A terminal modified polycarbonate having a high content of biogenic matter, excellent heat resistance, heat stability, moldability and moist absorption resistance and high surface energy and a manufacturing process thereof.The terminal modified polycarbonate has a main chain essentially composed of a recurring unit represented by the following formula (1): has a specific viscosity at 20° C. of a solution obtained by dissolving 0.7 g of the polycarbonate in 100 ml of methylene chloride of 0.2 to 0.5, and contains a terminal group represented by the following formula (2) or (3) in an amount of 0.3 to 9 wt % based on the main chain: wherein R1 is an alkyl group having 4 to 30 carbon atoms, aralkyl group having 7 to 30 carbon atoms, perfluoroalkyl group having 4 to 30 carbon atoms or a group represented by the following formula (4): wherein R2, R3, R4, R5 and R6 are each independently at least one group selected from the group consisting of an alkyl group having 1 to 10 carbon atoms, cycloalkyl group having 6 to 20 carbon atoms, alkenyl group having 2 to 10 carbon atoms, aryl group having 6 to 10 carbon atoms and aralkyl group having 7 to 20 carbon atoms, b is an integer of 0 to 3, and c is an integer of 4 to 100, X is at least one bond selected from the group consisting of a single bond, ether bond, thioether bond, ester bond, amino bond and amide bond, and a is an integer of 1 to 5.
