statistical nature of the step-growth polycondensation of AB2 type monomers; the statistical growth also causes the polydispersity index to increase with percent conversion (or molecular weight). We demonstrate that using controlled amounts of a specifically designed B3 core, containing B-type functionality that are more reactive than those present in the AB2 monomer, both the molecular weight and the
