The mechanism of polymerization reactions. I. The polymerization of styrene and methyl methacrylate

“…It has been widely supposed that the rate of polymerization of vinyl compounds is conditioned by the rate at which the catalyst first reacts with the monomer to give rise to active centres, and it has been considered that the subsequent process involving the building up of the polymer from the monomer takes place extremely rapidly and does not constitute a limiting factor. The basis for this viewpoint has largely been founded upon the experiments of Staudinger and Frost (1935) and of Schulz and Husemann (*936)5 who determined the molecular weight of the polystyrene formed at different stages in the process of polymerization and found that it was independent of the percentage polymerization.
