“…In previous work, scalar quantities like average molecular weight, polydispersity, degree of branching, or gel point have been successfully predicted. These results were mainly achieved either by statistical theories of Stockmayer [1,2] and Flory [3] or, later, by stochastic simulations [4] and a generating functions approach [5,6,7]. Most theoretical models that describe the polymerization of AB 2 monomer are based on the assumption that all functional groups of the same type are equally reactive, and react independently of one another.…”

“…24,25 Until now, hyperbranched polymerizations have been modeled exclusively by the exact kinetic approach: AB 2 polymerizations, in which the reactivity of B-groups on terminal units (rate constant k T ) is different from the reactivity of B-groups on linear units (rate constant k L * k T ), 26-30 AB 2 + B 3 polymerizations with 3 rates constants, 31,32 and AB f polymerization assuming non-equal reactivity of all B-groups (f rate constants). 33,34 The results reported are in agreement with Monte Carlo simulations, [35][36][37] and show increasing DB and broader molar mass distribution for AB f systems exhibiting positive substitution effects. The addition of a core molecule narrows the distribution but also limits the maximum achievable molar mass.…”

“…The number of unreacted B groups increases with increasing X n and f . A hyperbranched polymer is often characterized by the degree of branching DB [Holter et al, 1997;Jo and Lee, 2001;Kim, 1998;Lee et al, 2000]. For the hyperbranched polymer produced from AB 2 , there are three different types of repeat units: dendritic, linear, and terminal units defined as units having two, one, and no B groups reacted, respectively.…”
