New functional poly(N-vinylpyrrolidone) based (co)polymers via photoinitiated cobalt-mediated radical polymerization.
نویسندگان
چکیده
The photoinitiated cobalt-mediated radical polymerization enables the synthesis of novel α-functional and α,ω-telechelic polymers. In combination with ring-opening polymerization, it also produces new amphiphilic copolymers which self-assemble into flower-like vesicles in water.

The role of cobalt(II) complexes containing 2-formylpyrrolyl chelating ligands and phosphine ligands combined with a bromo-alkyl ester, an alkyl bromide or an azo compound in the formation of suitable initiator systems for vinyl monomer controlled radical polymerization was studied. The formation of syndiotactic-rich (Pr>0.7) poly(methyl methacrylate) (PMMA) and atactic (Pr=0.49) poly(styrene) ...
متن کاملLiving radical polymerization of acrylates and acrylamides mediated by a versatile cobalt porphyrin complex.
Living radical polymerization (LRP) of organic and water soluble acrylates and acrylamides was mediated by a versatile cobalt porphyrin complex (TMP-OH)Co. The capability of this cobalt complex to mediate LRP in both polar and non-polar media permits the direct synthesis of useful and previously difficult to prepare functional block copolymers.
