Abstract
This article studied the kinetics of the polycondensation of AB(g) monomers (where A and B denote different sorts of functional groups which can react with each other, and g is the number of B functional groups in a monomer), The molecular weight distribution function and the number- and weight- ave rage molecular weights had been derived, which are in agreement with those given by Flory using statistical approach: Numerical results show that the more the B functional groups in a monomer, the wider the molecular weight d istribution of the resulting hyperbranched polymer. The polydispersity incr eases with increasing the conversion of A groups, and increases very fast w hen the polycondensation approaches completion, This conclusion is qualitat ively in agreement with experimental data reported by Turner and coworkers.
