High-molecular weight star-shaped polystyrenes were prepared via the coupling 2,2,6,6-tetramethyl-1-piperidinylyloxyl (TEMPO) with divinylbenzene (DVB) in xylenes at 138 °C. The optimum coupling reaction conditions were determined, including the optimum ratio of the coupling solvent to DVB. Linear polystyrene oligomers were prepared in bulk styrene using benzoyl peroxide in the presence of TEMPO at approximately 130 °C under an inert atmosphere. The stability of the TEMPO-terminated oligomers was also investigated at coupling reaction conditions in the absence of DVB. The intrinsic viscosity measurements in NMP/0.02 P2O5 at 60 °C supported the formation of a star-shaped architecture.
