致孔剂对合成聚二乙烯基苯微球的影响

The Effect on Porous on the Synthetic Microporous Poly(Divinylbenzene) Microspheres

研究了碳酸钙和甲苯等致孔剂的用量对聚二乙烯基苯微球的粒径及其分布的影响.选择致孔剂并控制其用量,可以在一定范围内得到粒径窄分散的聚合物微球,粒径分散系数最小可达0.035.

The effect of dosages of different porogens on the particle size and distribution of the polymer microspheres is studied. By choosing different porogens and the dosage, polymeric micro- spheres with narrow distribution of the particle diameter can be prepared, while the coefficient of variation（CV） of the narrow dispersion polymer particle size can be as small as only 0. 035.
