The recovered vinyl acetate is free of polymerization inhibitor and may possibly contain some traces of polymerization initiator. To date iodine transfer polymerization itp organoheteroatom mediated polymerization omrp 28 37 cobalt mediated polymerization comrp and reversible addition fragmentation chain transfer raft polymerization have been proven efficient in the radical polymerization of vinyl esters. The photoinduced polymerization of vinyl acetate vac proceeded very fast even at 40 c with a catalytic amount of mn2 co 10 0 025 mol of vac or 5 0 mol of r i and completed within a few.
