摘要

In this study, we focus on the synthesis series of poly(4-vinylpyridine) (P4VP) containing quaternary alkyl bromides. The poly(4-vinylpyridine) (P4VP) was synthesized by conventional radical copolymerization and then the P4VP was quaternized by alkyl bromides containing chains consisting of 5 and 10 carbon atoms. Two copolymers series with three degrees of polymerization have been synthesized, the first poly[N-isopentyl(4-vinylpyridinium)] bromide P4VPIPBr (I); (II); (III) and the second poly[N-decyl(4-vinylpyridinium)] bromide P4VPBrD (I); (II); (III). The following techniques have been used to characterize the structure and composition of the cationic copolymers (P4VPIPBr) and (P4VPBrD), HNMR, conductimetry and viscometry.
