摘　　要：利用图形分析方法给出了不断引发、链增长自由基聚合反应的分子量分布函数，结合反应转化率曲线，利用隐函数方法和数学随机模拟法，得到了分子量分布曲线，利用计算结果讨论了不同终止形式及反应速率对聚合物分子量分布的影响，考虑反应体系的扩散控制，给出了苯乙烯本体聚合的分子量分布，得到与实验事实相一致的结论．Molecular weight distribution functions are obtained by graph analysis method. With different methods, such as conversion,the implicit function and Monte Carlo method, the difficulties in calculation are solved,molecular weight distribution curves are obtained. The influence of different termination and propagation rates on molecular weight distribution is discussed. Diffusion controlling in styrene bulk polymerization is concerned, polystyrene molecular weight distributions are obtained and the results are in agreement with the experimential observation.
