The rate of the thermal decomposition of potassium persulfate has been studied in an unbuffered aqueous solution a t 50Β°C in nitrogen atmosphere in the presence of vinyl acetate (VA) monomer (M). I t has been found that the initial rate of persulfate decomposition may be written as -d(&o,2-)/dt (S20
The initial rate of persulphate ( I ) decomposition at 50Β°C in the presence of nitrogen and methacrylonitrile (MAN) in an unbuffered aqueous solution (pH 4-7) may be written as: -d(SzOg-)/dt cc (MAN)1.29'0.05 x (I) 1.20-tO.04 in the concentration ranges of persulphate ( I ) (0.25-2.50) X lo-' ( m/d
