摘要
针对自由基聚合歧化终止和偶合终止两类机理生成的线型高聚物,应用统计物理的基本原理,对其分子量分布重新进行了理论推导,其方法简洁清晰,无须任何附加假定,导出FlorySchulz分布.结果有助于从另一方面理解FlorySchulz分布的物理学基础.
The Flory-Schulz distribution or the most probable distribution was deduced in literature, for the molecular weight distribution functions of linear polymers synthesized by condensation and addition reactions in some simple cases. An alternative theoretical way for deducing these equations is given according to the most probable state by using the basic principle in statistical physics for two model systems of typical linear polymers, the forming of which obeys the mechanism of free radical termination by combination and disproportionation. Then the Flory-Schulz distribution is obtained quite naturally. This theoretical method is simple and easy without any additional supposition. It is hoped that this study could be helpful in understanding the physical foundation of the Flory-Schulz distribution.
