The copolymerisations of styrene and methyl methacrylate, styrene and butyl acrylate, induced by the photo decomposition of benzoyl peroxide, have been studied and a full kinetic analysis of the reaction is presented. The introduction of small amount

An analysis of the mechanism of the thermal hydrogen-nitrous oxide reaction in silica vessels by the kinetic method has shown that it is a chain process. The experiments were confined to a comparatively narrow pressure range and the evidence for chai

In Part I it was shown that the process of activated diffusion of hydrogen into copper was composite including a true activated diffusion; the energy of activation for the hydrogen and deuterium migration differing from one another to an extent which

In this paper a critical review is made of the methods employed in part I of this series for the determination of the rate coefficients for the copolymerization of styrene and m ethylmeth ¬ acrylate. Evidence is presented which shows that the calcul

The polymerization of vinyl acetate has been studied at temperatures down to −40°C. by means of a specially designed apparatus. The object of the experiments is to preparer polyvinyl acetates of as linear a character as possible by working at low

When hydrogen atoms are produced by collisions between hydrogen molecules and excited mercury atoms in mixtures containing gases other than hydrogen, there is always a complication introduced by the fact that these gases may also react with the excit

A range of branched polymers has been prepared by condensing polyvinyl acetate chains containing a terminal carboxyl group, on to a radioactive, partially alcoholyzed backbone of polyvinyl acetate. The important advantage of this process over normal

For the investigation of the non-stationary state of chemical reactions and in particular polymerizations it is necessary to develop very sensitive means of recording small amounts of chemical change in short periods of time. For this purpose the cha

The effect upon degradation of cross-links, formed by copolymerizing small amounts of glycol dimethacrylate with the methyl methacrylate, and small amounts of acrylonitrile units in the chains has been investigated. Cross-links make no difference to
