Abstract
Block amphiphilic copolymer, poly(sodium styrenesulfonate-block-N-vinylcarb azole) (PSSS-block-VCz), was synthesized by nitroxide-mediated "living" fre e radical polymerization in homogenous solution. The procedure of the synth esis of poly(sodium styrenesulfonate) (PSSS) via the same technique was mod ified to reduce the amount of mediator and initiator needed. Camphorsulphon ic acid (CSA) and acetic anhydride (AA) were used as rate-accelerating addi tives in polymerization of PSSS and PSSS-block-VCz, respectively. The physi cochemical and photophysical properties of PSSS-block-VCz copolymer were de termined and discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
