在极性相反的单体对中,有些无需加自由基引发剂,就能进行所谓自动共聚合反应.带乙烯基的螺环原酸酯、碳酸酯和环缩醛或酮等是给电子单体,可能与接受电子的单体,如马来酸酐(Manh)进行自动共聚反应.至今,这方面研究工作报道甚少。 我们合成的2-苯基-4-亚甲基-1,3-二氧环戊烷(PMDO)能进行自由基开环聚合反应.本文研究它与受电子单体,如Manh、丙烯腈(AN)和甲基丙烯酸甲酯(MMA)的自动共聚反应. In the opposite polarity of the monomer pair, some do not need to add free radical initiator, can carry out the so-called auto-copolymerization reaction with spiro vinylorthosilicate, carbonate and cyclic acetal or ketone is to electronic single It is possible to conduct an autocatalytic reaction with electron-accepting monomers such as maleic anhydride (Manh) .There is little research work in this area. The synthesized 2-phenyl-4-methylene-1,3-dioxolane (PMDO) can undergo free-radical ring-opening polymerization.In this paper, AN) and methyl methacrylate (MMA) auto-copolymerization reaction.
