Linear viscoelasticity of incompatible polymer blends in the melt in relation with interfacial properties

A quite general characteristic of the rheology of incompatible polymer blends in the melt is their highly elastic behaviour at low frequencies, corresponding to long-time relaxation processes. For emulsions of Newtonian liquids, this property can be readily connected to interfacial tension a: in a macroscopic flow, suspended droplets of radius R are subjected on the one hand to a viscous drag r...

Glass Transition Temperatures In Binary Polymer Blends

Knowledge of the glass transition temperatures (Tgs) as function of composition reflects miscibility (or lack of it) and is decisive for virtually all properties of polymer-based materials. In this article, we analyze single blend-average and effective Tgs of miscible polymer blends in full concentration ranges. Shortcomings of the extant equations are discussed to support the need for an alter...

Collapse of a polymer chain in a melt of incompatible polymer chains

2014 We study the conformation of a linear polymer chain A in a melt of linear polymeric chains B of a different chemical species in the temperature domain where A and B chains are incompatible. We are lead to a strong contraction of the A chain similar to the usual collapse of a single chain in a poor solvent. However, the transition between the ideal and the collapsed state of the coils is mo...

Phase and microphase separation in polymer blends

When two different polymers are mixed, they usually demix because of the slight repulsive interaction that exists between their monomers. This is general and may be related to phase separation in two component mixtures. When the same polymer blend is cross-linked in the one phase region, elastic forces develop and do not let this to occur. There results a microphase separation, with coexistence...

Numerical Studies of Phase Separation in Models of Binary Alloys and Polymer Blends

We review some recent results concerning numerical studies of the CahnHilliard equation in three dimensions to describe the phase separation process in a mixture after a quench within the coexistence curve. We focus on the late time behavior for two experimentally relevant systems: binary alloys and binary polymer blends. We find that, in both systems, dynamical scaling with a time dependent ch...
