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...
acetone, is used to aggregate the polymer. The precipitated polymer is filtered and washed to remove the surfactant. The dried and purified polymer of very high molecular weight is in the form of a fine powder and is water soluble. The vinylamide homopolymer products are hydrolyzed to vinyl...
For example, for a series of polystyrene samples, the diffusivity of a range of organic vapours (acetone, benzene, etc.) decreased by a factor of almost ten as molecular weight increased from 10 000 to 300 000.15 However, in other systems, molecular weight has been found to have no ...
The relationship in acetone, [η] = 1.08 × 10 2 M 0.72 , was compared with literature data after the latter were converted to data corresponding to perfectly homogeneous fractions in acetone at 30°C., and was found to be in good agreement. Mean-square radii of gyration, 〈 S 2 〉,...

Results from a sedimentation velocity pattern indicated that the chain length distribution is much broader than random, which is in agreement with the ratio of the two molecular weight determinations. The polymer was fractionated by precipitation from acetone with hexane as precipitant. Addition of ...
IPA is active under reaction conditions because we had found there were gas phase components formation in the blank reaction (only IPA and catalyst, Figs.23,24). Acetone, methylsiobutylketone (MIBK), 2-hexanol, and 2,6-dimethyl-4-heptanone were observed in the liquid phase. ...
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...
