【摘要】 以甲基丙烯酸丁酯(BMA)、4-乙烯基吡啶(4-VP)、偏二氯乙烯(VDC)和二乙烯基苯(DVB)为原料,通过使用反应型乳化剂和氧化还原引发剂,采用无皂乳液聚合的方法,合成了具有不同粒径大小和不同粒径分布的稳定聚合物乳液。本文研究了反应型乳化剂相对于单体的摩尔比以及交联剂的用量对于乳液稳定性和热敏性能的影响。反应得到的聚合物纳米粒子具有较高的ζ电位,粒径分布窄。该聚合体系有助于在一定程度上进一步理解乳液聚合的反应机理。乳液的固含量可以高达40%,乳胶粒的粒径可以在40-300nm的范围内调整。使用红外光谱仪、颗粒度和ζ点位测试仪、热重分析仪和差示扫描量热仪对聚合物乳液的性能进行了分析。该乳胶粒子有望在水显影的热敏成像材料体系中得到运用。更多还原

【Abstract】 Stable polymer emulsion derived from Butyl Methacrylate (BMA), 4-vinyl pyridine (4-VP), vinylidene chloride (VDC) and divinylbenzene (DVB) with different size and distribution were prepared through soapless emulsion polymerization by using a reactive surfactant and a redox initiator. The influences of the quality ratio of the reactive surfactant to the monomers and the dosages of the cross-linking agent on the stability and thermal property of the emulsion were studied. The obtained polymer nano-particles have higher ξ potential, and the particle sizes have narrow distribution. This polymerization system can give some further understanding on the mechanism of emulsion polymerization .The solid content of the emulsion could be as high as 40% and the particle sizes could be adjusted in the range of 40～300nm. Otherwise, using infrared spectroscopy, size and ξ analyzer, gravitational thermal analysis and differential scanning calorimeter, properties of the emulsion latex were tested. This kind of latex may have applications in the development of water-developable thermal-sensitive material system.更多还原
