Phase diagrams of binary crystalline-crystalline polymer blends

Article Abstract:

A thermodynamically self-consistent theory is developed to establish binary phase diagrams for two-crystalline polymer blends by considering all interactions including amorphous-amorphous, crystal-amorphous, amorphous-crystal and crystal-crystal interactions. The calculated eutectic phase diagrams have displayed two solidus lines and two liquidus lines corresponding to the individual crystallizing components that are in equilibrium at the eutectic point, covering solid-liquid, liquid-solid and solid-solid coexistence regions.

Influence of acrylate arm topology on phase diagrams of mixtures of multiarm acrylate photocurative monomers and nematic liquid crystals

Article Abstract:

Cloud point determination is used to establish the phase equilibria of binary mixtures of liquid crystal and multiarm star acrylate derivatives as a function of the number of acrylate arms. It is found that the phase diagram of the branched/star molecule/solvent shifts to elevated temperatures with an increasing number of acrylate arms.

Theory of spin-Peierls transitions in chains of exchange clusters

Article Abstract:

A model based on the spin-Peierls transitions in chains of exchange clusters is used to study the magnetostructural phase transitions in polymeric heterospin complexes. The intercluster elasticity of the chain is the main factor that determines the phase transitions.
