Copolymerization of butadiene-styrene by means of an oxygen, dodecyl mercaptan, and iron and cobalt pyrophosphates system
Copolymerization of butadiene‐styrene in soap emulsion can be initiated by the interaction of oxygen and mercaptans catalyzed by traces of ferrous pyrophosphate and cobalt salts. A recipe is described which effects conversions of 53% within 36 hours at −1°. The resulting rubber is very soluble in be...

| Zusammenfassung: | Copolymerization of butadiene‐styrene in soap emulsion can be initiated by the interaction of oxygen and mercaptans catalyzed by traces of ferrous pyrophosphate and cobalt salts. A recipe is described which effects conversions of 53% within 36 hours at −1°. The resulting rubber is very soluble in benzene and has an intrinsic viscosity in the range of 3.5–4.36. |
