| 摘 要： | 聚合物乳液作为基本成膜物已在建筑涂料、木器漆和工业漆方面得到了广泛应用 .由于多数小分子染料与成膜物及其他组分的相容性不够好 ,常常导致这类彩色的聚合物产品涂刷时色泽不均、涂膜在使用过程中易于变色等缺陷 .将生色基团键合到聚合物分子链上 ,可以从根本上克服因相容性差而引起的染料小分子的迁移 ,同时还可以显著提高产品的保光保色性能1] .1 986年 ,ＢＲＩＡＮ通过丙烯酸酯与含偶氮基烯类单体的乳液共聚合 ,制备出了一类可直接用于纺织印染行业的彩色乳液2 ,3] .1 994年 ,ＳＯＳＮＯＷＳＫＩ等制备出了用于荧光标签的乳液聚合…

STUDY ON SYNTHESIS AND PROPERTIES OF SELF-YELLOWISHED LATEXES WITH PENDANT AZO GROUPS |
| |
| Abstract: | A series of self-yellowished polymer latexes were pr epared from styrene (St),butyl acrylate (BA) and 2-［4-(4′-nitrophenylazo)p henoxyl］ethyl acrylate (NAPEA) via semi-continuous emulsion polymerization.The influence of NAPEA on the polymerization,the latex properties and molecule wei ght of copolymer were investigated.The copolymerization of NAPEA with St and BA was preliminary confirmed using thin layer chromatography analysis.Experiments showed that the monomer conversion and the molecular weight of polymer decrease d obviously with the increase of the amount of NAPEA,and the electrolyte resist ance and mechanical stability of latexes were improved by incorporating NAPEA in to polymer chains. |
