Change in viscosities of polymeric liquid with concentrations of suspended particles

A theoretical model was proposed to explain the divergence of viscosities of polymeric liquids when irradiated with gamma rays, which still maintain the properties of Newtonian fluid. It has been proposed in the model, in contrary to the conventional explanation of mass divergence being the reason of viscosity divergence, that increase in the number of recombined polymers may lead to divergence in viscosity still allowing to maintain the Newtonian properties of the liquid. The validity of the model is examined using a more direct experiment by noting the effect of viscosity when some suspended particles are added in the liquid. Known quantities of fine powder of silicon was homogeneously mixed in the polydimethylsilicon ,commonly known as silicon fluid of known viscosity and change in viscosity with the concentration of silicon powder was measured using a differential viscometer developed. Preliminary results indicate the validity of the model. (author). 5 refs., 1 fig
