多孔高分子微球的制备研究 周锦鑫1,刘思思1,周虹峰1,顾顺超1 (1.上海交通大学化学化工学院化工系,上海,200240) 摘要:以苯乙烯,二乙烯苯为单体,引入混合溶剂作为致孔剂,采用悬浮聚合的方法制备了多孔交联聚苯乙烯微球,并通过有机萃取等方法带出致孔剂,形成永久性大孔.分析了搅拌速度,分散剂用量,致孔剂等因素对微球粒径分布和孔比表面积的影响,研究了不同工艺条件下的微球形态.结果表明,转速在180r/min左右,分散剂质量分数在0.15%左右时,可以制得粒径范围为0.2~0.8mm的聚苯乙烯微球,且微球具有良好的粒径分布.采用石蜡/甲苯,石蜡/乙酸乙酯为致孔剂时,可以形成纳米级小孔,且当石蜡/甲苯用量为86%时,孔比表面积可达到33.07m2/g,并随着交联剂用量的增加而增大. 关键词:悬浮聚合; 多孔微球; 粒径分布; 孔比表面积; suspension......
of anisotropic fluid, influence of un-symmetric stress tensor on material functions, vibrational shear flow of the fluid with small amplitudes and rheology of anisotropic suspension were reported. A new... of fluid, such as stability of hydrodynamic flow and orientational motion, were discussed. The results show that the polymer suspension systems exhibit anisotropic character. The PNC systems can exhibit......

to be digested under the simulated condition of the Bayer process and subsequently diluted with simulative Bayer red mud lotion, then the synthetic hematite or goethite suspension was obtained. The flocculation effect of self-made modified poly(acrylic acids) flocculants containing hydroxamic acid groups (abbreviated as HPAA) on the synthetic hematite or goethite suspension was studied. The experimental......
