The polymerization of methyl methacrylate in benzene was initiated by benzoyl peroxide and examined by kinetic analysis particularly from the point of view of primary radical termination. It is concluded that the velocity constant for dissociation of the benzoyloxy radical to give the phenyl radical

✦ Synopsis
The kinetics of vinyl chloride polymerization initiated by benzoyl peroxide doubly labelled with t4C and 3H were studied in 1,2-dichloroethane solution at 60 °. The importance of primary radical termination in the polymerization is examined by kinetic analysis and by analysis of polymers for combined initiator fragments.

The rate of vinyl chloride polymerization initiated by doubly labelled benzoyl peroxide in dichloroethane at 60 ° was measured dilatometrically. The extent of primary radical termination, evaluated from the assay of the polymer samples recovered at 10% conversion, is compared with values deduced fro
Vinyl acetate was polymerized in bulk and in benzene at 50°C using a wide range of concentrations of azobisisobutyronitrile. Values offk (the efficiency of initiator) and kr,,/klk p (the characteristic constant of primary radical termination) were found to be 0.53 and 2.00 x 104 respectively from da
## Abstract The radical polymerization behavior of vinyl monomers, such as styrene, methyl methacrylate (MMA), and vinyl acetate (VAc), in the presence of carbon black initiated by benzoyl peroxide (BPO) and 2,2'‐azobisisobutyronitrile (AIBN) in ionic liquid (IL) was compared with those in toluene.
