✦ Synopsis

Abstraet--A study on the polymerization of n-butyl methacrylate has been performed using 6°Co 7-rays. The kinetics were followed by a calorimetric method already used with methyl-and ethyl-methacrylate. In this case also, the rate of polymerization was found to be proportional to (dose rate) i over wide ranges of dose rate and temperature.

Rate constants for propagation and termination steps have been determined; the results agree with those for the other monomers and with literature data.

The gamma induced polymerizations of iso-butyl-(i-BMA) and dodecyl-(DDMA) methacrylates under non-stationary conditions have been studied, utilizing a calorimetric method already used for other methacrylates. For both monomers, the polymerization rate was found to vary linearly with (dose rate)½ at
