The subject of this work is the study of a new type of radical polymerization that occurs at elevated temperatures (80-100 °C) in mixtures of acrylates or (meth)acrylates and imine baes (IBA polymerization). The radical character of this polymerization is proven by the determination of copolymerization ratios and the reaction kinetics. On the basis of these facts and the hypothesis that the vinyl monomer acts as a co-initiator, calculations reveal the concentration of the initiating species to be very low ( Keq < 10−6). Furthermore, the choice of the reaction medium plays a crucial role on reaction kinetics and the average molecular weight of the resulting polymer. In combination with computational methodologies on the initiation, the multistep nature of this reaction is indicated. [ABSTRACT FROM AUTHOR]
