摘要：
Kinetics of the bulk thermal radical polymerization of methyl acrylate initiated by phenylazotriphenylmethane was studied and variation of the molecular mass characteristics during the polymerization process was determined. It is established that the polymerization proceeds by a two-stage pseudoliving mechanism, with the number-average MM of the increasing linearly with conversion and the gel effect being completely suppressed. The possibility to perform a controlled bulk polymerization of methyl acrylate at high temperature is demonstrated.
