Beschreibung
Zusammenfassung:	The invention provides a continuous polymerization reaction system and method for synthesizing a nylon 12 elastomer. According to the method, extra water is continuously injected into a pre-polymerization kettle to reduce the residual amount of a monomer, inert gas is continuously injected into a post-polymerization kettle to take away moisture to promote forward proceeding of a synthesis reaction, and polymerization is promoted. The method not only improves the polymerization reaction degree and efficiency, but also solves the problem of pipeline blockage. 本发明提供一种用于合成尼龙12弹性体的连续聚合反应系统和方法。该方法通过向预聚釜中持续注入额外水，降低单体残余量，并通过向后聚釜中持续注入惰性气体带走水分促进合成反应的正向进行，并促进聚合。该方法不仅提高了聚合反应程度和效率，还解决了管线堵塞问题。
