A simple method is described for the preparation of pure, dry alcohols, tritiated in the hydroxyl group. The polymerization of acrylonitrile initiated by tetrakis(dimethylamido)titanium(IV) has been terminated by quenching with tritiated isopropanol at varying reaction times, and the radioactivity o

Acrylonitrile was polymerized in an aqueous sulphuric acid-methanol medium by an electrolytically generated mediator species, titanium(III). Titanium(III)-dimethylglyoxime was used as the initiator redox system. The reaction was confined to the cathode compartment and was found to proceed via a free
The micellar effect on the kinetics of ceric ion-initiated polymerization of acrylonitrile (AN) in the presence of glucose was studied in the temperature range 40-50°C. The effects of concentration of the metal ion, monomer, sulfuric acid, substrate (glucose), emulsifier, some inorganic salt, and or
The polymerization of ~-caprolactam initiated by weak acids and bases has been reported previously:L z) To extend these observations to Lewis acids, a variety of compounds of tin (Lr) and (IV) have been examined as possible initiates. The following compounds have been found to be effective: stannic
