Abstract
A general kinetics equation was deduced for bifunctional polyesterification taken account of the changes of density during the reaction process. Kinetics parameters were given by using mol•L-1and mol•kg-1as the unit, respectively. The results show that the kinetic parameters expressed with mol•L-1are greater than those with mol•kg-1in the system of Neopentyi glycol/Maleic anhydride, and particularly the relative errors between them are increased along with the rise of temperatures.
