摘要
本文用淀粉接枝聚丙烯酰胺(S—g—PAM)与甲醛、二甲胺反应,合成了淀粉—胺甲基化聚丙烯酰胺接枝共聚物(S—g—APAM)。研究了各种因素对胺甲基化反应的影响。对钠型膨润土的絮凝性能研究表明:S—g—APAM与S—g—PAM及聚丙烯酰胺(PAM)相比,具有良好的絮凝效果。并研究了该胺甲基化的阳离子絮凝剂水溶液的流变学性质。
In this paper, the graft copolymer of starchaminomethy lated polyacry-
lamide ( S-g-APAM ) was prepared by the aminomethy lation of graft
copolymer of starch- polyacry lamide (S-g-PAM) with formalinand
dimethyl amine. The factors effecting the aminomethy lation were
investigated.On the basis of the experimental results of floccu lation on Na
-type bentonite suspention,S-g-APAM is a better flocculant compared with
PAM, S-g-PAM.In addition the rheology properties of the aqueous solution
of S-g-APAM were studied.
