摘要：
A comparison of styrene polymerization initiated with mono and difunctional nitroxide compounds and the synthesis of block copolymers using nitroxide-mediated radical polymerization (NMRP) is reported. Nuclear magnetic resonance and mass spectroscopy were used to characterize the crystals produced. The use of dinitroxide to initiate styrene polymerization resulted in the formation of telechelic polystyrene and its subsequent use to initiate NMRP of a second monomer led to the formation of an A-B-A triblock copolymer.
