摘要
通过采用小角Ｘ－射线散射法测定大孔标准苯乙烯－二乙烯苯共聚物的结构，发现交联度２０％以上的大孔共聚物在数埃至数百埃的范围内具有分形结构，分形维数为２．２～２．
The structure of the title copolymers was investigated with small angle X ray scattering. It was found that fractal structure existed in the macroporous resins with crosslinking degree exceeding 20%,and the fractal dimension was 2.2 to 2.8 in the range of several Angtroms to several hundred Angstroms.
