叙述了一种对于孔性交联聚合物的实验可测得的溶剂总吸收率中区分骨架溶胀和孔洞吸收的简便方法.用此方法测量了作为色谱载体的乙基苯乙烯一二乙烯基苯共聚物微球的孔度和骨架溶胀度.从稀释剂溶剂化能力的影响的研究,阐明了成孔机理.进一步的理论分析得出:孔性交联聚合物的孔度价对聚合开始时油相中单体的体积分数尸胜和聚合以后聚合物骨架在稀释剂中的溶胀度Q之间的依赖关系为其中、是接近于1的参数,相当于转化率与体积收缩率的比值,从而使Millar等人得到的成孔经验规律得到了理论的说明.
A simple method for distinguishing the skeleton swelling and hole absorption from experimentally measurable total solvent absorption of a porous cross-linked polymer is described. This method was used to measure the copolymerization of ethylstyrene-divinylbenzene Pore size and swelling degree of microspheres.According to the study of the influence of the solvating ability of diluent, the pore forming mechanism is clarified.Further theoretical analysis shows that the pore size of the porous crosslinked polymer has a great influence on the pore structure of the oil phase The volume fraction of monomer in the monomer and the polymer after polymerization in the diluent swelling degree Q dependence between them, where is a parameter close to 1, the equivalent of conversion rate and volume shrinkage ratio, so that Millar and others obtained the rule of hole forming experience has been the theoretical description.
