端羟基丁二烯丙烯腈共低聚物的合成及其力学性能Ⅱ.均匀组成的液体共聚物的合成

Synthesis of Hydroxy-Terminal Butadiene-Acrylonitrile Cooligomer and Mechanical Properties .

根据共聚物组成的计算方法，合成了组成均匀的端羟基丁二烯与丙烯腈液体共聚物并用ＮＭＲ观察和计算了该液体聚合物的序列分布。

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 more reactive monomer. The calculation method is derived, which is capable of controlling the composition of cooligomer durin the course of reaction. Some cooligomers of acryonitrile and butadiene with comparatively homoge neous composition have been prepared using this replenishing method. The mechanical Properties are studied.
