Abstract: The samples having almost the same molecular weight but different MWD were pre-pared by precipitation fractionating and then mixing in solution. The influence of MWD on the viscoelastic properties of raw rubber was studied using the methods of GPC and stress relaxation. The effect of low molecular weight fractions on the density of chain entanglement networks and the contribution of high molecular weight fractions to the viscoelastic properties of raw rubber were also examined.
