Synthesis of Hydroxy-Terminal Butadiene-Acrylonitrile Cooligomer and Mechanical Properties . The Calculation Method of Controlling the Composition

通过分批聚合，制备具有均匀组成的共聚物。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。

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. The calculation method is derived, which is capable of controlling the composition of co-oligomer during the course of reaction. Some co-oligomers of acryonitrile and butadiene with comparatively homogeneous composition have been prepared using this replenishing method. The method would be useful for other two-component copolymerization process.
