Thermodynamics of oligomeric binary mixtures of polyethylene glycol and polypropylene glycol methylethers

Thermodynamics of mixtures containing oxaalkanes. 5. Ether+benzene, or +toluene systems

“…The sources of G E m and V E m data used are given in Table 6. Finally, in order to evaluate V i and Ä Ti values at T / = 298.15 K, we have applied the well-known equations for the density, ,˛p and (=˛p/Ä T ) given elsewhere [45].…”

Thermodynamics of (1-alkanol+linear monoether) systems

“…The reduction parameters for P Ã M and T Ã M are calculated from mixing rules [22,23]. In order to calculate the reduction parameters of pure compounds at T 6 ¼ 298.15 K, the following expressions were used to determine the values of a p and c (=a p /j T ) [49]:…”

Neutron Scattering from Polymers: Five Decades of Developing Possibilities

“…The work at Imperial was focused on experimental observation of miscibility limits in binary polymer blends as a function of molecular weight, using light scattering (30)(31)(32), the effects of pressure on miscibility, and attempts to measure the enthalpy of mixing in low-molecular weight systems (33). While making sure we were aware of the different theoretical descriptions being developed, I never felt that these were adding much to my understanding of polymer thermodynamics.…”
