Özet
In this study, synthesis, characterization, partial hydrolysis, and salt formation of poly(2-hydroxyethyl methacrylate)-co-poly(4-vinyl pyridine), (poly(HEMA)-co-poly(4-VP)) copolymers were investigated. The copolymers were synthesized by free radical polymerization using K2S 2O8 as an initiator. By varying the monomer / initiator ratio, chain lengths of the copolymers were changed. The copolymers were characterized by gel permeation chromatography (GPC), viscosity measurements, 1H and 13C NMR and FTIR spectroscopies, elemental analysis, and end group analysis methods. The copolymers were partially hydrolyzed by p-toluene sulfonic acid monohydrate (PTSA·H2O) and washed with LiOH(aq) solution to prepare electrorheological (ER) active ionomers, poly(Li-HEMA)-co-poly(4-VP). © 2006 Wiley Periodicals, Inc.
