Abstract
The sequential copolymerization of 2- or 4-vinyl pyridine has been attempted with the aim of preparing linear triblock (ABC) copolymers. The use of either of these two monomers was found to lead to extensive, although incomplete, star-branched polymer formation. The linking reaction in this anionic polymerization of vinyl pyridine appears to be the result of the participation of the NCH moiety in the pyridine ring along with the vinyl group. The addition of 4-vinyl pyridine to dicarbanionic chains in benzene or tetrahydrofuran was found to lead to both branched and crosslinked polymer. The morphology of a model star co-branch block terpolymer containing polystyrene, polyisoprene, and poly(4-vinyl pyridine) segments was examined by transmission electron microscopy.
