Continuous stirred tank polymerization of vinyl acetate has been investigated under conditions that promote branching and broadening of the molecular weight distribution. T-butanol and azobis-isobutyronitrile were the solvent and initiator respectively. Residence times ranged from 1.5 to 8.3 hr, con
The branched structure formation during free radical polymerization of vinyl acetate is investigated in detail by application of the computer simulations on the basis of the Monte Carlo sampling technique. Simulations are made for the whole molecular weight distribution (MWD), the MWDs for polymer m
Measurements were made of the value of the lumped kinetic constant k p /k t 0.5 of vinyl acetate in different solvents and with different initiators. This quantity was evaluated using the well-known conversion vs. time approach in dilute solutions using both azo-bis-isobutyronitrile and benzoyl pero
