本文重点介绍了聚乙醇酸的溶解度参数和相互作用参数。用43种溶剂对聚乙醇酸进行了溶出性能研究。通过优化计算得到了聚乙醇酸的汉森三维溶解度参数和总参数。聚乙醇酸的δd、δp、δ和δ分别为17.094(J/cm ~ 3)1/2、8.206(J/cm ~ 3)1/2、7.912(J/cm ~ 3)1/2和20.546(J/cm ~ 3)1/2。用特性粘数法和基团贡献法计算了聚羟基乙酸的总参数,证明了该方法的可靠性。计算了聚乙醇酸与43种溶剂的相互作用参数和溶解度参数“距离”。相互作用参数的计算结果与Flory-Huggins提出的聚合物和溶剂完全互溶的标准相符合。
This article focuses on the solubility parameters and interaction parameters of polyglycolic acid. 43 solvents have been used for polyglycolic acid to study the dissolution property. Then the Hansen three-dimensional solubility parameters and total parameter of polyglycolic acid were obtained by an optimization calculation. The values ofδd,δp,δhandδfor polyglycolic acid have been obtained as 17.094 (J/cm3)1/2, 8.206 (J/cm3)1/2, 7.912 (J/cm3)1/2and 20.546 (J/cm3)1/2. It was proved that the total parameter of polyglycolic acid is creditable by intrinsic viscosity approach and group contribution method. The values of the interaction parameter and the solubility parameter “distance” between polyglycolic acid and 43 solvents have been calculated. The results of the interaction parameters accords well with the standard of complete miscibility suggested by Flory–Huggins for polymers and solvents.
