不久前我们曾报导了聚丙烯酰胺的水溶液在室温或55℃时有可能与过氧化氢发生均相氧化反应,形成聚丙烯酰胺大分子过氧化物.这种水溶性的聚丙烯酰胺大分子过氧化物可引发烯类单体的接枝共聚,得到相应的碳链接枝共聚物。利用这种简便的接枝方法不仅可以合成一系列具有综合性能的接枝共聚物新品种,而且对大分子过氧化物引发烯类单体接枝共聚反应历程的研究也具有一定意义。 Not long ago we reported that polyacrylamide aqueous solution may undergo homogeneous oxidation reaction with hydrogen peroxide at room temperature or 55 ° C to form a polyacrylamide macromolecule peroxide. This water-soluble polyacrylamide macromolecule Oxides can initiate the graft copolymerization of the vinyl monomers to give the corresponding carbon chain graft copolymers. Using this simple grafting method not only can synthesize a series of new varieties of graft copolymer with comprehensive properties, but also have certain significance for the study of the graft copolymerization reaction of macromolecule peroxide initiated olefin monomer.
