  公开号：EP0104391A2

  公开（公告）日：1984-04-04

  A melt-polymerization process is described for the preparation of thermoplastic polyamides and polyesteramides by reaction of the appropriate organic diisocyanate and dicarboxylic acid or difunctional carboxylic acid-terminated polyol. The process, which can be conducted in a batch or continuous manner, comprises the steps of admixing the reactants (preferably in the liquid state), heating the mixed reactants at reaction temperature in a manner such that eliminated carbon dioxide can be vented freely, alowing the reaction to proceed until approximately 25 - 95 percent (preferably at least 50 percent) of the theoretical carbon dioxide has been eliminated and reducing the resulting intermediate to a powder before completing the reaction by melting, homogenizing, and devolatilizing.

  本发明描述了一种熔融聚合工艺，通过适当的有机二异氰酸酯和二羧酸或二官能羧酸封端多元醇的反应制备热塑性聚酰胺和聚酯酰胺。该工艺可以分批或连续进行，包括以下步骤：混合反应物（最好是液态），在反应温度下加热混合反应物，使排出的二氧化碳可以自由排出，让反应进行到大约 25-95%（最好是至少 50%）的理论二氧化碳被排出，并将生成的中间体还原成粉末，然后通过熔化、均质和脱溶剂完成反应。
