阅读说明：本技术 具有减少的光气过量的制备聚碳酸酯的方法 (Method for producing polycarbonates with reduced phosgene excess ) 是由 R·巴赫曼 V·米歇尔 J·海尔 F·可克 于 2020-03-30 设计创作，主要内容包括：本发明的主题是通过相界面法由至少一种二羟基二芳基烷烃、光气、至少一种催化剂和至少一种链终止剂制备聚碳酸酯的方法,其中该方法通过给定的用于分散水相和有机相的能量输入能够实现减少的光气过量。此外,该方法提供具有低的低聚物比例和低的二-链终止剂碳酸酯比例的聚碳酸酯。(The invention relates to a method for producing polycarbonates by the phase interface method from at least one dihydroxydiarylalkane, phosgene, at least one catalyst and at least one chain terminator, wherein the method enables a reduced phosgene excess by means of a given energy input for the dispersion of the aqueous and organic phases. In addition, the process provides polycarbonates having a low proportion of oligomers and a low proportion of di-chain terminator carbonates.)
