迄令为止,有关磁场对化学反应影响的研究,主要是小分子自由基反应,而对聚合反应的研究甚少。1981年周朝华、苏致兴报道了磁场对聚甲基丙烯酸甲酯立体构型的影响。随后,N.J.Turro研究了磁场对苯乙烯乳液聚合的影响。结果表明,磁场对苯乙烯的聚合速率及聚合物分子量有影响。 本文首次报道磁场对醋酸乙烯酯乳液聚合反应速率,聚合物分子量及热稳定性的影响。
Up to now, the study on the influence of magnetic field on chemical reaction is mainly the free radical reaction of small molecules, but little research on the polymerization reaction. 1981 Zhou Zhaowa, Su Chi Hing reported on the magnetic field on the three-dimensional configuration of polymethyl methacrylate. Subsequently, N.J.Turro studied the magnetic field on the styrene emulsion polymerization. The results show that the magnetic field has an influence on the polymerization rate of styrene and the molecular weight of the polymer. This paper reports for the first time the magnetic field on the vinyl acetate emulsion polymerization rate, the molecular weight and thermal stability of the polymer.
