A novel way to synthesize star polymers in one pot by ATRP of N-[2-(2-bromoisobutyryloxy)ethyl]maleimide and styrene
A one-pot approach to synthesize star polymers by atom transfer radical polymerization (ATRP) of N-[2-(2-bromoisobutyryloxy)ethyl]maleimide (BiBEMI) with a large excess of styrene (St) was described. It was based on preferential consumption of BiBEMI, as an inimer, through its copolymerization with St, to form a branched intermediate in situ as the multifunctional core, which initiated homopolymerization of the excessive St to produce a star polymer. The kinetic studies exhibited two polymerization stages corresponding to the formation of the core with a faster propagating rate and the formation of arms by homopolymerization of St, respectively. 1H NMR spectra showed that in core formation stage random copolymer was formed. Analysis of the basic hydrolyzed products of the core by MALDI-TOF mass spectroscopy confirmed the branched structure of the core. A “6”-shaped polystyrene was also formed simultaneously, and its structure was confirmed by MALDI-TOF mass spectroscopy. Lowering the reaction temperature and using less excessive St could decrease the content of this polymer. Star polymers were characterized by 1H NMR, hydrolysis, and intrinsic viscosity.
