摘要
对含间苯二甲酸 (IPA)共聚酯固相缩聚进行了研究 ,建立了球形颗粒中可逆化学反应和小分子三维扩散共同控制的模型 ,得到了在氮气保护下 ,2 0 0～ 2 2
The solid state polycondensation of copolyester containing isophthalic acid is studied.A model which is controlled by reversible reaction and small molecular three dimensional diffusion within spherical pellet is established,the reaction kinetics parameters of solid state polycondensation under nitrogen protection at 200～220 ℃ are available.
