Abstract
The efficiency of chain scission of raw Hevea by molecular oxygen increases rapidly with increase of temperature to a limiting value of about 6.2 molecules of oxygen per bond broken. This value is close to the theoretical for destruction of one isoprene unit per bond broken, which leads to the inference that the higher efficiencies which have been reported for oxidation of vulcanized rubber may be the result of scission at the points of cross-linking.Keywords
