| 摘 要： | 以三羟甲基丙烷三甲基丙烯酸酯（ TMPTMA ）为内交联单体,苯乙烯（ St ）、甲基丙烯酸甲酯（ MMA）、丙烯酸丁酯（ BA）和甲基丙烯酸（ MAA）为共聚单体,采用半连续核壳乳液聚合工艺合成了自交联聚丙烯酸酯乳液（ T-PAE）。考查了TMPTMA添加量与添加方式对乳液聚合稳定性以及涂膜性能的影响。研究发现：随着TMPTMA含量的增加,T-PAE乳液聚合的稳定性降低,聚合凝胶率增大,乳胶粒的平均粒径下降；涂膜的耐介质性能和交联密度相应提高,合适的TMPTMA加入量为总单体质量的0．5%~1．0%。 |

| Abstract: | The crosslinked polyacrylate latexes（ T-PAE） with core-shell structure were synthesized by semi-batch core-shell emulsion polymerization process with trimethylol propane trimethacrylate （ TMPTMA ） as a crosslinker, methyl acrylate（ MMA） ,styrene（ ST） ,butyl acrylate（ BA） and methacrylic acid（ MAA） as co-monomers. The effects of the contents and added methods of TMPTMA on the emulsion and film properties were investigated. The results indicated that the polymerization stability and particle sizes of T-PAE decreased with the amount of TMPTMA in-creased,while the water-or alcohol-resistance properties of cured film improved due to increasing of the crosslinked degrees of T-PAE film,the optimal TMPTMA dosage is 0. 5~1. 0wt%. |
| Keywords: | crosslinked polyacetylate emulsion trimethylol propane trimethacrylate polymerization stability |
