    • A terminal-modified polycarbonate that is high in the content of substance derived from organism, excelling in heat resistance, thermostability, moldability and moisture absorption resistance, and that is high in surface energy. The terminal-modified polycarbonate is one whose main chain consists essentially of a repeating unit of the formula: (1) having a specific viscosity of 0.2 to 0.5 at 20°C with respect to a solution obtained by dissolving 0.7 g thereof in 100 ml of methylene chloride, the polycarbonate containing 0.3 to 9 wt.%, based on the main chain, of terminal of either of the formulae: (2) (3) wherein R1 is a C4-C30 alkyl, etc., or a C7-C30 aralkyl, or a C4-C30 perfluoroalkyl, or a group of the formula: (4) and wherein X is at least one bond selected from the group consisting of a single bond, an ether bond, a thioether bond, an ester bond, an amino bond and an amido bond, and a is an integer of 1 to 5. Further, there is provided a process for producing the terminal-modified polycarbonate.
