Notes:
The influence of carbon tetrachloride, pentachloroethane, 1,2-dichloroethane, 1,1,2-trifluorotrichloroethane, benzene, and 1,3,5-trimethylbenzene on the velocity of the benzoyl peroxide-initiated polymerization of trifluorochloroethylene was studied over a wide range of concentrations. Throughout the entire range of variation of concentration of trifluorochloroethylene, there was no simple relation between concentration and velocity of polymerization; the solvents in these systems did not behave merely as diluents. The influence of the solvents on the polymerization velocity of trifluorochloroethylene varies greatly: some solvents behave as an inert medium for example, 1,1,2-trifluorochlorethane, benzene; other solvents, however, act as inhibitors 1,3,5-trimethylbenzene. Finally, certain chlorinated hydrocarbons carbon tetrachlorides, pentachloroethane, 1,2-dichloroethane show a maximum in the reaction velocity at a certain ratio to the monomer. Various possible hypotheses are discussed which could explain the observed anomalous dependence of increased polymerization velocity, on a lowering of the concentration of trifluorochloroethylene.
