β-(α-三甲基胺基)乙基苯乙烯同丙烯酰胺自由基聚合的竞聚率测定

Competitive Rate Measurement of Free Radieal Polymerization between β-(α-Trimethylamine) Ethylstyrene and Acrylamide in Aqueous Solution.

本文叙述了β－ （α－ 三甲基胺基） 乙基苯乙烯（ Ｓ Ｎ） 的实验室制备及同丙烯酰胺（ Ａ Ｍ） 水溶液自由基聚合反应。在８ ％ ～１０ ％ 的转化率下测定 Ｓ Ｎ 单体单元在共聚物链上的组成。用 Ｆｉｎｅｍａｎ － Ｒｏｓｓ 法作图求得 Ｓ Ｎ 同 Ａ Ｍ 两单体的竞聚率值为γ１ ＝ ０ ．２７ ，γ２ ＝ ０ ．８８ ，并用此竞聚率值对 Ｓ Ｎ 同 Ａ Ｍ 共聚行为进行了探讨。

his paper describes the preparation of β-(α-trimethylamine) Ethylstyrene(SN) in lab and free radical polymerization between it and acrylamide in aqueous solution. First, the composition of SN monomers in copolymer chain is measured at low conversion rate. Second, competitive rates of these two kinds of monomer are determined by drawing using Fineman-Ross method. Finally, competitive rate's influence upon free radical combined polymerization's behavior between SN and AM is discussed.
