摘要

应用气相色谱法研究了温度对丙烯腈-丙烯酸甲酯水相沉淀共聚合竞聚率的影响

测得30℃时r1=0.96

r2=1.18;40℃时r1=0.83

r2=1.17;50℃时r1=0.70

r2=1.17;60℃时r1=0.68

r2=1.10

竞聚串与反应温度的关系为:1nr1=-4.043+1207/T

1nr2=-0.01360+51.68/T。发现共聚物沉淀粒子的表面吸附作用对该共聚体系竞聚率的温度依赖性有很大影响。

Abstract

The effect of temperature on the Monomer Beactivity Eatios(MRR) of copolymerization of acrylonitrile with methyl acrylate in aqueous solution was studied by means of gas chromatography. We obtained r1 = 0.96

r2 = 1.18 at 30℃; r1 = 0.83

r2 = 1.17 at 40℃; r1 = 0.70

r2 = 1.17 at 50℃; r1 = 0.68

r2 = 1.10 at 60℃.The relationship between MRR and temperature is as follows:Inr1 = -4.043 + 1207/T

Inr2 = - 0.01360 + 51.68/T.It has been discovered that the temperature dependence of MRR is considerably affected by the adsorption on the deposit particles of the copolymer for this copolymerization system.
