Get your polymerization off to a fast start.
Use PPG peroxydicarbonate initia tors. They're faster and more efficient than other peroxides c o m m o n l y used for free radical polymerization. They give high yields, linear conver sions and l o w residuals. W e make five types: IPP (diisopropyl peroxydicarbonate), NPP ( d i - n - p r o p y l peroxydicarbonate), SBP (di-sec-butyl peroxydicar bonate), EH Ρ ( d i - 2 e t h y l h e x y l peroxydicarbonate), and BPIC ( t - b u t y l peroxy isopropyl carbonate). W e can custom formulate any of the five, diluted in solvent to your specifications. Important properties and typical applications: Product
