Abstract: A process for purifying a polycarbodiimide comprising (a) providing a mixture comprising a polycarbodiimide and a carbodiimidization catalyst; (b) separating carbodiimidization catalyst from the polycarbodiimide by subjecting the mixture according to (a) to a first distillation, (c) adding an entrainer to the first bottom product obtained from (b) to obtain a mixture; (d) further separating carbodiimidization catalyst from the polycarbodiimide by subjecting the mixture obtained from (c) to a second distillation.

Abstract: A continuous process for the preparation of polyoxazolines comprises mixing monomers, an initiator, and optionally an additive, feeding the mixture into at least one tubular reactor segment with a feed side and an outlet side, and polymerizing the mixture to form the polyoxazolines. A tubular reactor segment comprises a mixer for forming a mixture comprising monomers, an initiator, an additive, a terminating agent, and/or a functionalizing agent, at least first and second tubular reactor segments, and addition devices for the first and second tubular reactor segments.
Abstract translation: 用于制备聚恶唑啉的连续方法包括将单体，引发剂和任选的添加剂混合，将混合物进料到具有进料侧和出口侧的至少一个管式反应器段中，并使混合物聚合以形成聚恶唑啉。 管状反应器段包括用于形成包含单体，引发剂，添加剂，终止剂和/或官能化剂的混合物的混合器，至少第一和第二管状反应器段，以及用于第一和第二管式反应器的添加装置 细分。
