摘要

本文分别研究了聚氧化乙烯(PEO)、聚丙烯酰胺(PAM)在水溶液中的超声波降解和超声波嵌段共聚.PEO的降解反应服从1/(?)对辐照时间的线性关系

而PAM的降解反应则服从1/(?)对辐照时间的线性关系.用IR、DTA和NMR分析了共聚物的结构

在共聚物的红外光谱中未发现PAM分子中的氢原子形成接枝点的迹象

所得产物为嵌段共聚物.

Abstract

The kinetics of the ultrasonic degradation of aqueous solution of poly-acrylamide and poly(ethylene oxide) as well as ultrasonic block copolymeriza-tion of aqueous solution of the mixture of polyacrylamidepoly (ethylene oxide) were studied respectively. The degradation reaction of poly (ethylene oxide) follows a linear relationship between 1/ (Pt - P) and irradiation time

while that of polyacrylamide follows a linear relationship between 1/ (Pt - P)1/2 and irradiation time. As the structure of the copolymer was identified by IR

DTA and NMR

the hydrogen atoms in polyacrylamide remain unchanged

and the copolymer prepared is a block copolymer.
