Curing theory of the A_ai–B_bj type polycondensation. (II) sol‐gel distribution

Abstract

An alternative way is proposed to approach the sol-gel distribution of A,,-B,, type polycondensation by taking into consideration intramolecular reaction. The equations deduced basically from the definition of the sol fraction and the chemical equilibrium of reactants in this paper can be reduced to those of Tang Au-chin's and Miller's expressions. Comparing experimental with theoretical values, we found that the results of this paper are closer to the real cases than those of other authors.
