(Elsevier, 1973-12)
The preparations and characterizations of several monomeric vinylimidazolium salts are presented from the quaternizations of 1-vinylimidazole and 2-methyl-1-vinylimidazole with n-alkyl iodides and with dimethyl sulphate. ...
Random coil dimensions of poly(diethyl siloxane)
(Elsevier, 1978-04)
A sample of high molecular weight poly(diethyl siloxane), [Si(C2H5)2---O---]x, (PDES) was separated into a series of fractions by means of liquid-liquid precipitations. Four of the fractions were studied by osmometry and ...
