Dendritic units hyperbranched polymer characterization

Hyperbranched polymers are characterized by their degree of branching (DB). Hie DB of polymers obtained by the step-growth polymerization of AB2-type monomers is defined by Eq. (2.1) in which dendritic units have two reacted B-groups, linear units have one reacted B-group, and terminal units have two unreacted B-groups191 ... [Pg.57]

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 AB2, 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. The degree (fraction) of branching (DB) is given by... [Pg.176]
