Abstract
Multi-alkylated surfactants of partially-quaternized 2-vinylpyridine telomers having 2-4 alkyl chains (xRn-2VPQ; x and Rn mean the number of lipophilic alkyl chains and alkyl chain length, respectively) were derived from telomers with polymerization degree (Pn) ca. 5 obtained as salts of hydrochloric acid. Surface activitiy was voted to be highly affected by alkyl chain length and number of chains. Surface tension of 3.9R8-2VP+Q and 3.4R12-2VP+Q with Pn ca. 5 solutions (pH 2) was 28-29mN m-1 at critical micellar concentration. Surface activity was affected by Pn of telomers and xRn-2VP+Q having 3-4 octyl or dodecyl chains with Pn ca. 5 showed greater surface activity than xR12-2VP+Q having 3-6 dodecyl chains with Pn 10-20.
