    • The invention relates to a method of preparing silicone copolycarbonates which incorporate both blocky and random substructures. Such silicone-containing copolycarbonates are useful in the preparation of a variety of molded articles such as optical disks. The structure of the compositions prepared by the method of the invention is determined by the method of preparation used and may be used to control physical properties. The copolymers are prepared by forming in a first step an intermediate silicone copolycarbonate possessing either a blocky or random structure and reactive endgroups, and then appending additional structural in a second step which is complimentary to the first step and produces a product silicone copolycarbonate having both random and blocky substructures. The repeat units I and II appended in the second step may be the same or different as those repeat units I and II incorporated in the first step.
    • 本发明涉及一种制备掺入块状和随机亚结构的硅氧烷共聚碳酸酯的方法。 这种含有机硅的共聚碳酸酯可用于制备各种模塑制品如光盘。 通过本发明方法制备的组合物的结构由所用的制备方法确定,并可用于控制物理性质。 共聚物通过在第一步骤中形成具有块状或无规结构的中间体硅氧烷共聚碳酸酯和反应性端基,然后在与第一步相互补充的第二步中附加另外的结构,并产生具有两个随机的产物硅酮共聚碳酸酯 和块状亚结构。 在第二步中附加的重复单元I和II可以与在第一步骤中结合的重复单元I和II相同或不同。
