    • The present invention provides methods of producing high molecular weight polymer. A method of forming polycarbonate includes the step of combining in a reaction mixture a diaryl carbonate, a transesterification catalyst, an aliphatic dihydroxy compound, and a diacid compound in a reactor system. The temperature and pressure of the reactor system are adjusted to a first reactor setpoints and the reaction mixture is monitored to detect initiation of the exothermic oligomerization reaction. The reactor setpoint are adjusted to second reactor setpoints after detection of initiation of the exothermic oligomerization reaction. The reactor system is maintained at the second reactor setpoints to allow the reaction mixture to react to form an oligomer mixture. The oligomer mixture is then introduced to a polymerization reactor system operating under melt polymerization conditions sufficient to polymerize the oligomer mixture to a Mw of at least 9,000 g/mol (PC) and to remove the phenolic byproduct from the oligomer mixture to form polycarbonate.
    • 本发明提供高分子量聚合物的制造方法。 形成聚碳酸酯的方法包括在反应混合物中在反应器体系中将碳酸二芳基酯,酯交换催化剂,脂族二羟基化合物和二酸化合物混合的步骤。 将反应器系统的温度和压力调节至第一反应器设定点,并监测反应混合物以检测放热低聚反应的起始。 在检测到放热低聚反应的起始之后,将反应器设定点调整到第二反应器设定点。 将反应器系统保持在第二反应器设定点以允许反应混合物反应以形成低聚物混合物。 然后将低聚物混合物引入到在熔融聚合条件下操作的聚合反应器系统,该条件足以将低聚物混合物聚合至至少9,000g / mol(PC)的Mw,并从低聚物混合物中除去酚类副产物以形成聚碳酸酯。

    • According to the present invention a method for grafting a chemical compound to a predetermined region of a support substrate (4) is disclosed, comprising: a) irradiating selectively the support substrate with electromagnetic radiation and/or particle radiation in order to both define said predetermined region and to form at least one reactive functional group or a precursor thereof in said predetermined region of the support substrate; b) exposing the irradiated support substrate to said chemical compound or to a precursor thereof. Therefore, only these very few steps are needed to effectively grafting the desired chemical compound, such as an organic compound, to the predetermined regions of the support substrate. Moreover, the irradiation step can be carried out in a vastly flexible manner and allows to generate numerous distinct shapes of the predetermined regions. Further, micro- or nano-scale regions in the support substrate capable of forming reactive functional groups or precursors thereof upon exposure to particle or electromagnetic irradiation can be easily achieved.

    • A poly(carbonate-co-ester) block copolymer is synthesized using synthetic strategies that can be incorporated into conventional melt facilities that are commonly used in the production of polycarbonate polymers. The polycarbonate block of the poly(carbonate-co-ester) copolymer is derived from a polycarbonate reaction mixture comprising an aromatic dihydroxy compound and a carbonic acid diester, such as bisphenol A and diphenyl carbonate, respectively. The second block of the copolymer is derived from a polyester prepolymer, the polyester prepolymer comprising a diol, diacid or diester, and at least one monomer that is selected to advantageously incorporate desired properties into the poly(carbonate-co-ester) copolymer. The polyester prepolymer is introduced to the polycarbonate reaction mixture to form the poly(carbonate-co-ester) copolymer. Properties of the copolymer can be altered by varying numerous conditions of the reaction.
