dc.descriptionWith the purpose of enhancing the reaction rate of nitroxide-mediated radical polymerization of styrene (NMRP) in presence of TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxy), keeping the livingness of the system, the effect of a bi-functional initiator has been examined, a new approach. The monomer used was the styrene, the stable radical was TEMPO, the mono-functional initiators were BPO and Luperox TBEC, and the bi-functional initiator was Luperox L531. The polymerization reactions were carried out in ampoules at 125°C, according to the bi-molecular technique. The conversion was evaluated by a gravimetric method, and the molecular weight distribution and the polydispersity of the polymer were analyzed by SEC (Size-Exclusion Chromatography). The effects of the use of the bifunctional initiator and the mono-functional ones with different half-life times have been evaluated. It was demonstrated that by using the bi-functional initiator L531, the reaction rate was increased when comparing to the performance of the mono-functional initiatiors, under the conditions of the reaction.
