    • PROBLEM TO BE SOLVED: To improve the impact resistance properties or the dependency of the toughness on the thickness of a polycarbonate-based resin molding.
      SOLUTION: The polycarbonate-based resin is obtained by melt-kneading 99-80 pts.wt. polycarbonate resin and 1-20 pts.wt. epoxy group-containing liquid isobutene-based oligomer having a number-average molecular weight of 200-3,000 obtained by subjecting the terminal vinylidenes of a liquid isobutene-based oligomer having a main chain structure of a specific repeating unit and a terminal vinylidene structure to ethylene oxidation. The polycarbonate-based resin is improved in impact resistance and its dependency on the thickness not at the expense of moldability, transparency and weatherability and exhibits an excellent performance in applications to substitute plate glass for outdoor use such as vehicle windows and building materials.
