The Synthesis of Polystyrene-B-Poly(4-Vinylpyridine) by Nitroxide-Medium Controllable Free Radical Polymerization

Abstract:

In this paper, a system polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) were synthesized by nitroxide-medium controllable free radical polymerization. PS-b-P4VP were characterized by 1H-nuclear magnetic resonance (1H-NMR), infrared spectrum (FTIR) and gel permeation chromatography (GPC). The results have indicated that diblock copolymers can be prepared and with molecular polydispersities in the range of 1.08 to 1.31. The structure of diblock was showed by 1H-nuclear magnetic resonance.
