引入空基和空键的概念,高分子的聚合可以用Ising 模型来研究.不同聚合度的分子和单体,都是处于亚稳态,其间的数目分布不能使用热平衡绕计方法得到.当出现催化作用时,系统的稳定状态自由能极小.对于单环,因为位形空间的降温轨道不能到达有序状态的代表点,聚合反应不可能给出大的单环产物.对于含有N 个结构单元的长链,理论给出高限温度T_c=2J/k In(1/2N).理论结果与聚合物的聚合和解聚实验很好地符合. The introduction of space-based and space-bond concept, polymer polymerization can be used Ising model to study different degrees of polymerization of molecules and monomers are in the metastable state, the number distribution can not be obtained using the heat balance method. For the monocyclic ring, the polymerization reaction can not give large monocyclic products because the orbit of the space-shaped space can not reach the representative point of the ordered state.For a single ring, The long chain of units, the theory gives the maximum temperature T_c = 2J / k In (1 / 2N) .The theoretical results with the polymer polymerization and depolymerization experiments in good agreement.
