A laminar jet instrument was used to measure the molecular diffusivities of oxygen with 0.995 partial pressure into distilled water and aqueous solutions of eight long chained polymers. Molecular diffusivity of oxygen into distilled water was found to be 1.95 x 10m5, at 20°C which compares favorabl
