摘要: 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[1]

Abstract: This paper reports the effects of a magnetic field on the emulsion polymerization of vinyl acetate initiated by oil-soluble photo-sensitized initiator, benzoin. It was found that the polymerization rate and molecular weight of the polymer increase with the increase of magnetic field intensity in a lower magnetic field, and decrease fastly with increasing magnetic field intensity in a higher magnetic field.
