摘要

This work deals with the kinetics of co-condensation polymerization of AB2 and AB monomers

giving expressions of the two-dimensional molecular weight distribution function and the number/weight average molecular weights of the resulting copolymers. The two-dimensional molecular weight distribution depends on two indices

n and l

which are the respective numbers of AB2 and AB units in a copolymer species. The evolution of the two-dimensional weight and zdistributions during the co-condensation polymerization has been evaluated systematically. Finally

the two-dimensional distribution was transformed into a one-dimensional molecular weight distribution with only one variable (the molecular weight of the products instead of the degree of polymerization). The calculated results show that the highly branched copolymer has a very broad molecular weight distribution when the co-condensation polymerization approaches completion.
