| 摘 要： | 通过核-壳微乳液聚合技术合成了具有较高玻璃化转变温度(Tg)的苯丙微乳液,研究了核-壳单体用量比、壳单体组成、交联剂、聚合物极性对乳液最低成膜温度(MFT)的影响;同时比较了三种成膜助剂对乳液MFT的作用。研究发现,成膜温度随核-壳比的增大而上升;交联剂羟甲基丙烯酰胺(NMA)能有效地降低成膜温度;醇酯—12是一种良好的成膜助剂,同一成膜助剂对极性不同的乳胶粒子MFT的降低效果明显不同。

| Abstract: | A styrene-acrylate microemulsion with a comparatively high glass transition temperature （Tg） had been synthesized via core-shell microemulsion polymerization. The influences of ratio of core to shell monomers, composition of shell monomers, crosslinking agent and polarity of polymer on minimum film forming temperature （MFT） were studied; and the functions of three auxiliaries were compared. The resuhs showed that the MFT rose when increasing the core-shell ratio; the crosslinking agent n-methylolacrylamide （NMA） could effectively decrease MFT; alcohol ester was a good auxiliary for film forming; and the decrease effects of identical auxiliary on MFT of polymer particles with dissimilar polarities were obviously different. |
