The tube theory has made a detailed description for the linear polymer entangled system, while the behavior of entangled star polymers is still determined by a qualitative prediction. In this paper, the dynamical simulation of a three-arms star polymer in the grid model is presented. We record the diffusion coefficient [Formula: see text], the relaxation time for the arms of star polymer [Formula: see text] and some other parameters corresponding to different branch length. Therefore, results that are inconsistent with the theoretical begin to emerge.

网格模型中星形聚合物的弛豫行为

管理论对线型聚合物纠缠体系做了详细的描述，而纠缠的星形聚合物的行为仍由定性预测决定。本文介绍了网格模型中三臂星形聚合物的动力学模拟。我们记录了扩散系数[公式：见正文]、星形聚合物臂的弛豫时间[公式：见正文]以及与不同分支长度相对应的一些其他参数。因此，与理论不一致的结果开始出现。
