丁二烯与丙烯腈共低聚反应中共聚物组成的控制

摘要/Abstract

摘要： 在二元共聚反应中,为了制备具有均匀组成的共聚物,对于分批聚合,在反应过程中须补加消耗较快的单体以保持单体的浓度比为常数。本工作提出了为控制共聚物组成在反应过程中补加单体的计算方法,它不仅适用于丁二烯与丙烯腈的共低聚反应,也适合于其它二元共聚反应。用这种方法制备了具有均匀组成的丁二烯与丙烯腈共低聚物。

Abstract: In preparing copolymer with homogeneous composition by batch process in two-component copolymerization reaction it is necessary to keep the monomer ratio constant by replenishing the fraction of the more reactive monomer.In this paper a calculation method for monomer feeding is derived, which is capable of controlling the composition of cooligomer during the course of reaction.Some cooligomers of acryloni-trile and butadiene with comparatively homogeneous compositions have been preparedusing this replenishing method. The method would be useful for other two-component copolymerization process.
