摘要

正

A series of acrylic ester copolymers with viologen group as pendant were synthesizedthrough the reaction of MMA-EBA （Ethenyl bromoacetate） copolymer with 4-（4’-pyridyl）-N-alkyl （or arylalkyl） pyridiniums. These viologen copolymers can exchange their anionwith NH

in methanol to improve their solubility in organic solvents such as DMFand acetone. Compared with the corresponding low molecular viologens

these viologencopolymers have relatively lower color development rate under UV light and fade fasterin air due to less affinity to photo-reductant and deficiency of association between theircation radicals. Their photofatigue resistant ability is also slightly better than that of lowmolecular vinlogens.
