A new method has been developed for measuring the number of molecules of oxygen required ( 6 ) to cause a main chain scission in peroxide vulcanisates of natural rubber. This method is based on experimentally derived relationships and is not dependent on statistical theories of rubber elasticity. Th

The cure index and apparent activation energy of vulcanization of one grade of natural rubber (SMR L) and two grades of epoxidized natural rubbers (ENR 25 and ENR 50) were studied in the presence of three types of antioxidants [viz., 2,2Πmethylene-bis(4-methyl-6-tertbutylphenol) (AO 2246), poly-2,2,
Being polar and compatible with poly(viny1 chloride), epoxidized natural rubber (ENR) is similar in behaviour to acrylonitrile butadiene rubber (NBR). To assess the extent of this similarity, the mechanical properties of 50/50 blends of PVC with these two rubbers were compared. Their response to the
