Title: Viscometric method for determining rubber content in guayule (Parthenium argentatum Gray)

Abstract

The viscosity of cyclohexane solutions of guayule rubber increased with rubber concentration. The relationship allows measurements to be made of the rubber content of guayule material by a viscometric technique that is simple and inexpensive. This viscometric method gave results comparable to other methods currently in use to determine rubber content, such as the gravimetric and infrared spectrophotometric methods. Oxidative degradation of the rubber solutions can affect viscosity but these effects can be minimized by avoiding light, by use of appropriate antioxidants, and by storage of samples under refrigeration.
