Thiophene decorated block copolymers templated from poly(styrene-alt-maleic anhydride)-block-poly(styrene) one-shot block copolymer: effect of thiophene inclusion on morphology
- 303 Downloads
Poly(styrene-alt-maleic anhydride) copolymer and poly(styrene-alt-maleic anhydride)-block-poly(styrene) block copolymer with narrow molecular weight distributions were synthesized by nitroxide mediated radical polymerization (NMP) and the anhydride units were selectively converted to thiophene units. The thiophene decorated poly(styrene-alt-maleic anhydride) copolymer was emulsified in water, resulting in rod-like or cylindrical morphologies with diameters ≈ 90 nm while the non-decorated copolymers and thiophene decorated block copolymer resulted in spheres.
