溶液聚合法制备防泳移剂及其对涂料染色性能的影响

Preparation of antimigrant with solution polymerization method and its effect on pigment dyeing behavior

采用共聚单体经溶液聚合制成防泳移剂,研究了单体的筛选、共聚单体质量比、引发剂用量、反应温度、反应时间对防泳移剂合成的影响,并测试了防泳移剂用量对涂料染色性能的影响,优化的防泳移剂合成条件为：m（甲基丙烯酸）∶m（丙烯酰胺）∶m（顺丁烯二酸酐）=6∶8∶1、w（引发剂）=4.0%（对单体质量）、85℃反应5 h.用防泳移剂6 g/L进行涂料染色,所得色织物防泳移性5级、干摩擦牢度4~5级、湿摩擦牢度3~4级、手感较软.

Antimigrant was prepared by comonomers with solution polymerization method.The effects of selection of monomer,mass ratio of comonomers,dosage of initiator,reaction temperature and time on the syn-thesis of antimigrant were investigated.The influence of antimigrant dosage on pigment dyeing behavior was tested.The optimal synthesis conditions were： m（methacrylic acid） ∶m（acrylamide） ∶m（maleic anhydride） =6 ∶8 ∶1,w（initiator）=4.0%（on the mass of monomer）,reacted at 85 ℃ for 5 h.The antimigration level of fabric pigment dyed with 6 g/L of antimigrant was grade 5,dry crocking fastness was level 4～5,wet crocking fastness was lev-el 3～4,the handle was soft.
