Multicyclic polymers exhibit distinct physical properties, such as lower hydrodynamic volume and radii, reduced viscosity and different glass-transition temperatures. However, due to the synthetic difficulty and separation problem, obtaining multicyclic polymers remains challenging. In this report, we describe the synthesis three-arm star polystyrene using ATRP and “Click” reaction. After “Click” reaction, theta-shaped and branched polystyrene were simultaneously formed. Prepared theta-shaped and branched polymer can be easily separated by selective precipitation owing to their solubility difference. Separated multicyclic polystyrenes were characterized by GPC, MALDI-TOF MS, 1H NMR and FT IR analysis. |
