Abstract:

The Block copolymer polystyrene-b-poly(acrylic acid)-b-polystyrene(PSt-b-PAA-b-PSt) wassynthesizedviareversible addition-fragmentation chain transfer polymerization by using styrene as the firstmonomer.The architectures of the macro-chain transfer agent PSt-CTA and the block copolymers wereconfirmed by FTIR and1H-NMR.GPC analysis was used to estimate the molecular weight and the molecularweight distribution of the copolymers,the numer-average molecular weight of macro-chain transfer agent PSt-CTA was 8320,a...
