Electroinitiated polymerization of acrolein has been achieved by controlled potential electrolysis at the reduction peak potential of the monomer for direct electron transfer. Kinetics and type of mechanism of the polymerization have been investigated. the structure of the polymer has also been examined by IR spectroscopy. in a separate experiment, a small amount of CCI4 was added to a polymerization system. Since the reduction peak potential of CCI4 appears at a more anodic region than that of acrolein on mercurized platinum, initiation proceeds via the electrolytic product of CCI4. the direct and indirect initiation mechanisms are compared. It is found that electroinitiated polymerization of acrolein carried out by direct electron transfer from cathode to monomer (in the absence of CCI4) proceeds simultaneously via radical and anionic mechanism.
