Generally, the viscosity of polymers decrease as temperature increases and it increases as concentration increases, but the rates of these changes are largely dependent on the source of the polymer. In this work, the polymer investigated is extract from Irvingia Gabonensis; a West African polymer that is used as a food ingredient and also used in various industries such as in cosmetics and pharmaceuticals. Irvingia Gabonensis extract has also been proposed as a prospective polymer for enhanced oil recovery and can serve as a drilling fluid with high cuttings carrying capacity. The viscosity of this polymer in water at concentrations of 0 – 10g/l and temperature range of 10 – 60oC were determined. Obtained results were used to derive a mathematical model that describes how the viscosity varies with change in its concentration and temperature. The derived equation, experimental results and modeled results are presented. It is observed that results from the model match well with experimental results; rendering the model a useful tool in material science. The model can be used for viscosity prediction of Irvingia Gabonensis polymer in water provided the values of concentration and temperature fall within the range considered in this work.
