Abstract
It is well known that some molecular compound is formed by carbon tetrachloride and amine, and that the addition of the amine and copper to the telomerization system of carbon tetrachloride and vinyl compound affects the distribution of molecular weight of the telomers. The authors investigated the mechanism of dissolution of copper in carbon tetrachloride-amine system and applied this effect to the surface treatment of metals.
A local cell was formed among copper, carbon tetrachloride, and an aliphatic amine. When copper was dissolved in the solution, an active chemical species was formed, by action of which vinyl monomer was polymerized. The rate determining step in the local cell was pesumed to be the cathodic reaction, in which the electron was transferred from copper to carbon tetrachloride-amine complex, and trichloromethyl radical was formed.
