Summary 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.
