采用水溶性引发体系研究了丙烯酰胺的均聚以及与几种乙烯基单体的共聚反应。探讨了引发剂、温度、单体浓度及加热时间对所得聚合物相对分子质量及其分散性能的影响。对产物的结构特性和相对分子质量分布进行了表征,并考察了共聚物的分散性能。丙烯酰胺共聚物同均聚物相比,分散性能有明显的改善。
The water-soluble initiator system was used to study the homopolymerization of acrylamide and copolymerization with several vinyl monomers. The effects of initiator, temperature, monomer concentration and heating time on the relative molecular mass of the obtained polymer and its dispersibility were discussed. The structural characteristics and relative molecular mass distribution of the product were characterized, and the dispersion properties of the copolymer were investigated. Acrylamide copolymer homopolymer compared to the dispersion performance has been significantly improved.
