Viscosity‐molecular weight relationship for cellulose acetate in acetone Careful viscosity and osmotic pressure measurements with a membrane of known reliability are reported for 14 fractions of cellulose acetate prepared by repeated refractionation, For molecular weights up to 115,000 the following relatio...
The cellulose was nitrated, and, after fractionation according to differences in solubility in acetone/water, the DP pattern of labeled or unlabeled cellulose nitrate was determined by viscosity measurements. A low (DP < 500) and high DP-fraction (DP > 2500) of cellulose were predominant in ...
PURPOSE: To measure the molecular weight distribution of cellulose acetate by solving the cellulose acetate with acetone and measuring resulting solution given to a gel permeation chromatography (GPC) with acetone used as moving bed. ;CONSTITUTION: The device consists of a moving bed storage tank 1...
FOLLICLE stimulating hormone (FSH) was obtained from powdered human pituitary dried with acetone and purified in two ways: ( a ) by the method of Amir, Barker, Butt and Crooke 1 and ( b ) by the cellosolve extraction procedure of Butt, Crooke and Wolf 2 followed by fractionation on DEAE...
As polymermolecular weightincreases, the number of chain ends decreases. The chain ends represent a discontinuity and may form sites for permeant molecules to be sorbed intoglassy polymers. For example, for a series ofpolystyrenesamples, the diffusivity of a range of organic vapours (acetone, benze...
