Abstract
Cobalt(II)acetylacetonate is an effective mediator for the radical polymerization of vinyl acetate in bulk, suspension and miniemulsion, even when high molar mass is targeted. The mechanism, which basically relies on the reversible combination of the growing poly(vinyl acetate) (PVAc) chains with the cobalt complex, has been analyzed by UV-visible and NMR spectroscopies. The influence of both the temperature and the concentration of the initiator and the cobalt complex has also been investigated. With the macromolecular engineering of PVAc and poly(vinyl alcohol) (PVOH) in mind, a series of end-functional chains and PVAc (PVOH) containing block copolymers have been successfully synthesized.
