Referee's report by Harry Work Melville, on a paper 'Studies in polymerization. I. A method for determining the velocity constants in polymerization reactions and its application to styrene' by Clement Henry Bamford and Michael James Stewart Dewar Sectional committee: Chemistry Recommended for publication in Proceedings, with modifications.The opening part of the paper should be completely modified, as the author ignore the fact that the problem has already been solved and results have been published. They need to provide experimental proof that the equation they refer to is valid for their polymers. Until this is done, the theoretical part of the paper rests on an 'absolutely insecure foundation'. [Published in Proceedings of the Royal Society A, 1948].
