偶氮二异丁腈引发甲基丙烯酸甲酯微乳液聚合 - The results of the uni - factor experiments and perpendicular experiments show their best mechanic synthesizing craft as followed : nvp ( 10 % wt ) , kh570 ( 20 % wt ) , hema ( 70 % wt ) , initiator ( 0 . 2 % wt ) , crosslinker ( 20 % wt ) , reacting 20 hours under 80 c . the factors which influenced organic silicon modified pvp hydrogel soft contact lens material ' s swelling capabilities were researched , which included temperature , monomer content , ion concentration etc . the experiments showed the equation swelling content ewc improved with the increase of nw , droped with the increase of kh570 and ion concentration , improved then droped with the raise of temperature , and hydrogels got the least ewc at 45 c . experiment carried on todiscuss water dehydration mechanism of organic silicon modified pvp hydrogel soft contact lens materials , which showed dehydration process could be divided into evaporating stage and diffusing stage
正交实验结果表明， nvp ? hema ? kh570共聚物的机械性能最佳时，其合成工艺条件为： nvp用量10 (质量百分含量，下同) ， kh570用量20 ， hema用量70 ，引发剂aibn用量0 . 2 ，交联剂nmba用量0 . 2 ，反应温度为80 ，反应时间16h 。讨论了单体配比、溶胀温度、离子浓度等因素对有机硅改性pvp水凝胶软接触透镜材料溶胀性能的影响。实验得出：水凝胶材料的平衡溶胀度ewc随单体nvp含量的增加而增大， ewc随kh570用量的增加而减小，随离子浓度的增大而略微降低，随溶胀温度的升高先稍微下降后有所提高， 45时平衡含水量最低。 - Monodisperse ( coefficient of variation 5 % ) polystyrene microspheres in the size range of 1 . 0 ~ 10 m are prepared by dispersion polymerization in ethyl alcohol reaction media using polyvinylpyrrolidone ( pvp ) as a steric stabilizer and 2 , 2 ' - azobisizobutyronitrile ( aibn ) as an initiator in suitable condition
