The dilute solution properties of poly[2,2-propane-bis (4-phenylthiocarbonate)] (PPhTC) in various solvents have been studied by viscosity, osmotic pressure and gel permeation chromatography measurements. The unperturbed dimensions were determined, and the viscometric relationships were established.
Molecular characteristics for pullulan, a polysaccharide produced by a fungus Aureobasidium pullulans, were measured by light scattering, viscometry, and gel-permeation chromatography. From the experimental data the Mark-Houwink-Sakurada viscosity equation in water a t 25OC was determined for sample
