Description

Solution polymerization of vinyl acetate was carried out in redox systems, one component of which was diisopropyl peroxydicarbonate (IPP) at 0°C to 40°C.<BR>IPP-N, N′-dimethylaniline (DMA) system have very effective catalytic activity for vinyl acetate polymerization in methanol solution and the most effective mole ratio is [IPP]/[DMA]=1/1.The apparent activation energy of polymerization was 11.4 kcal/mol and the initial rate of polymerization (Rp) was proportional to the term of [IPP]1/2×[DMA]1/2.The system in methanol solution was slightly pink and the polymer obtained was slightly yellow, on the other hand, in bulk and in ethylacetate or benzene solution, the systems were colorless.<BR>The polymerization using IPP only as a initiator was also examined and the apparent activation energy of polymerization was 18.5 kcal/mol and Rp was proportional to [IPP]1/2.
