THE KINETICS AND MECHANISM OF POLYESTERIFICATION OF BINARY ACID AND BINARY ALCOHOL

Scientia Sinica (1975)

Yao‐ren Fang Chu-Gen Lai Jialin Lu Mu-Kuo Chen

In this paper the kinetics and mechanism of polyesterification without using foreignstrong acid as catalyst are presented. It is considered that in the process of reaction theremay exist two kinds of reaction mechanism in the system of polyesterification. Owingto the change of dielectric constant and the viscosity of the system, the relative contents ofthe two mechanisms convert into each other with the change of reaction degree.In thelater period of reaction,hydrolysis of polyester produced by the residue water will beconsidered. The kinetic equation deduced in this paper can fully explain the experimental data ofFlory and Wu et al.
