✦ Synopsis

Abstraet--A report is given of effects of tetramethyithiuram monosulphide (TMTM) upon the polymerization of styrene at 80 °; it can act as both an initiator and a retarder and there is great sensitivity to light. Experiments with ~4C-TMTM show that transfer to initiator is important. Attempts were made to measure the rate of dissociation of TMTM spectrophotometrically and by isotope dilution analysis. At room temperature in benzene solution, there are exchange reactions between TMTM and the corresponding disulphide.
