ELECTRON MICROSCOPE STUDIES OF POLYMER DEGRADATION

Degradation studies have been carried out on a dilute solution of a polyacrylamide, Polyhall 402, in distilled water with the aid of a simple rheometer, employing a capillary tube operating in the turbulent flow regime. The degraded samples, collected after each pass through the rheometer were analysed with the aid of an electron microscope. The analysis showed how the polymer molecules fracture under turbulent shear with the fragments in solution approaching asymptotically an average molecular weight of approximately 1,000,000 after a number of passes.
