针对二元共聚反应,在分批聚合中制备组成相同的共聚物,提出了为控制共聚物组成在反应过程中补加活性较大单体的计算方法。并根据这种方法合成了端羟基丁二烯-丙烯腈共低聚物。该方法也可用于其它二元共聚反应。

In preparing copolymer of the same composition by batch process in two-component copolymerization 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 acrylonitrile and butadiene with relatively the same compositions have been prepared using the replenishing method. The method would be useful for other two-component copolymerization process.
