Abstract
Measurements of the refractive index increment of a variety of Hevea rubber samples and a range of narrow distribution synthetic polyisoprenes have been made at a wavelength of 615 nm and a temperature of 40C. Evidence that the increment decreased with molecular weight at low values (below 100 kg mol-1) was found for both the natural and synthetic materials. Soluble non-rubbers in the natural material were found to act effectively as a diluent. Otherwise there appeared to be little difference between the natural and synthetic polyisoprene; the average values measured for the refractive index increment were respectively 0.135 mig-1 and 0.133 mlg-1. A high molecular weight fraction of natural rubber gave a figure (0.147 mlg-1) well above that obtained for the other natural polyisoprene samples.
