六十年代以来,苏联发表了一系列文献,涉及乙烯基单体与腐植酸聚合制造土壤改良剂和钻井泥浆处理剂,但就一些基本问题未见阐述,诸如:(1)腐植酸中的多官能及含有的自由基对烯类单体自由基聚合的影响;(2)腐植酸与单体的接枝效率及腐植酸与单体接枝聚合机理;(3)接枝共聚物与共混物在性能上的差异,本文针对上述第一个问题进行了研究。采用膨胀计法研究了在不同类型煤炭腐植酸存在下,过硫酸钾引发丙烯酰胺溶液的聚合反应动力学。
Since the 1960s, the Soviet Union has published a series of articles on the polymerization of vinyl monomers with humic acid to make soil improvers and drilling mud treatment agents, but some basic problems such as: (1) (2) grafting efficiency of humic acid and monomer and humic acid and monomer graft polymerization mechanism; (3) graft copolymers and blends In terms of performance differences, this article addresses the first issue above. The swelling kinetics of acrylamide solution initiated by potassium persulfate in the presence of different types of coal humic acid was studied.
