【摘要】 提出基于实验基础之上的高分子凝胶化反应的分形几何研究方法，即以苯乙烯－二乙烯苯凝胶化反应为例，由激光及小角Ｘ光散射技术测定反应中分子质量、尺寸及散射光强角度依赖性，经分形理论处理数据，以分数维参数定量描述化学反应，在更深层次上揭示了化学反应规律。更多还原

【Abstract】 he approaches are as follows: Using the copolymerization of styrenedivinylbenzene as an example, firstly, the molecular weights, sizes and the dependence of intensity scattered on angles were determined during this gelation by laser light scattering and samall angle Xray scattering, respectively; secondly, these data were processed with fractal theory, thirdly, the gelation was described quantitatively in terms of fractal dimension and finally the rule of gelation of polymer was revealed at the more essential level.更多还原
