Abstract

The development of a modified iodometric method of estimating the concentration of tert-butyl peroxyisobutyrate (tBPIB) in natural rubber (NR) latex is described. The decomposition of tBPIB in NR latex in the presence or absence of fructose was found to be a first-order reaction with respect to tBPIB concentration. The initial rate of tBPIB decomposition however was found to be half order with respect to initial tBPIB concentration. The effect of reaction variables on the rate of tBPIB decomposition is discussed. The activation parameters are calculated from the rate measurements. The significance of the kinetics of tBPIB decomposition in relation to tBPIB reaction and the kinetics of crosslinking is discussed.
