Abstract

The thermal polymerization of methyl isopropenyl ketone in bulk as well as in solutions of benzene, toluene, ethyl benzene, cyclohexane and methyl cyclohexane has been studied at 80°C. It has been found that there is no inhibition period ivolved. There is an acceleration in rate in those cases where the medium became heterogeneous and the polymer precipitated out. The kinetic order of the reaction with respect to the monomer concentration is found to be 2 in case of all the solvents. Benzoyl peroxide eatalysed polymerization has also been studied in bulk and in solutions of toluene and is found to follow the expected square root relation with respect to the catalyst concentration. The value of δ (=kt1/2/kp) for methyl isopropenyl ketone at 80°C. has been determined in bulk and in solutions of toluene and is found to temain sensibly constant, the value being 35.98 in case of bulk polymerization.
