Studies of polyester/chlorinated poly(vinyl chloride) blends

Antiplasticization of a polyamide: a positron annihilation lifetime spectroscopy study

“…The k parameter has been related to the strength of the interactions between both components [48,49]; i.e. for systems where the chain mobility is impeded by the interactions values higher than 1 are usually obtained for k: In our case, k parameter takes a value of 1.37, which reflects the strong interactions present in the T/PVPh blend, in good agreement to the values obtained for other mixtures constituted by PVPh [50].…”

Miscibility, thermal properties and polymorphism of syndiotactic polystyrene/poly(styrene-co-α-methyl styrene) blends

“…In fact, it is an adjusting parameter which has been served as a semi-quantitative measurement of the interaction strength between the mixed components [28,29]. Fig.…”

Viscous flow properties and phase behaviour of oil–resin blends

“…5, the experimental values of T g can be satisfactorily fitted to a Gordon-Taylor equation [8,9,16]: where T g o and T g r are the glass transition temperatures of the individual components, oil and resin, v o and v r are their respective volume fractions, and k is a non-dimensional semi-empirical parameter, with a value of 1.72 for the blends studied. This last parameter is the ratio between the differences in the thermal expansion coefficients of the rubbery and the glassy states for components 1 and 2.…”
