摘　　要：首次用动态光散射方法跟踪了苯乙烯本体聚合全过程的光子相关光谱，研究了散射强度、聚合物平移扩散系数、分子量分布随聚合反应的变化，获得了有关聚合体系和活性分子链物理状态的信息，如玻璃态的微观非均一性及活性分子链比较刚硬等。It is the first time to trace the whole process of styrene bulk polymerization continuously using the dynamic light scattering experiment.The scattering intensity, the diffusive coefficients and the molecular weight distribution of the polymer during the process of the polymerization were studied, and some information about the physics states of the polymerization system and the active polymer chains was obtained, such as the microinhomogeneity of the glassy state and the rigidity of active molecular chains and so on.
