“…Branching may influence thermodynamic interactions between the polymer and solvent,1–3 rheological properties,4, 5 Θ temperature,2, 6 glass‐transition temperature,7 melting behavior and crystallization,8 phase separation of polymer mixtures,9, 10 curing behavior of synthetic resins,11 mechanical properties, solubility, chemical resistance, and solution viscosity. In some cases the branching can have counteracting impact; for example, the change of glass‐transition temperature with increasing degree of branching is the result of two effects: the increased number of end groups increases the chain mobility and free volume, whereas the introduction of branch points reduces the chain mobility and free volume.…”
