Water partitioning in 'dry' poly(ethylene oxide) alcohol (CmEn) nonionic surfactant—a proton NMR study
Autor: Markus M. Hoffmann, Jack D. Fox, Megan E. Bennett, Donald P. Wyman
Publikováno v: Journal of Colloid and Interface Science. 287:712-716
A proton NMR titration study is presented where in small increments quantities of water were added to "dry" CmEn nonionic surfactant. For a particular range of compositions, two resonances for the water/hydroxyl protons were observed that display lar

Method for separating intramolecular and intermolecular interactions which influence polymer glass temperatures
Autor: Donald P. Wyman
Publikováno v: Journal of Applied Polymer Science. 11:1439-1448
It is shown that the glass temperature (Tg) for homopolymers of the type CH2CXYcan be expressed by a simple additive equation involving two terms: (1) a parameter E which is directly related to the molar cohesion energy and (2) a parameter Es* which

The reaction between butyllithium and trans-stilbene in benzene solvent yields a mixture of 1,2-diphenylhexyllithium and 1,2,3,4-tetraphenyloctyllithium. These compounds readily disproportionate to 1,2-diphenylhexane, 1,2,3,4-tetraphenyloctane, 1,2-d
