Rheology of polymer blends with matrix-phase viscoelasticity and a narrow droplet size distribution
A Hamiltonian framework of non-equilibrium thermodynamics is adopted to construct a set of dynamical continuum equations for a polymer blend with matrix viscoelasticity and a narrow droplet size distribution that is assumed to obey a Weibull distribution function. The microstructure of the matrix is described in terms of a conformation tensor. The variable droplet distribution is described in t...
متن کاملLinear 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...

متن کاملThermodynamics of Polymer Blends 2
This chapter summarizes the thermodynamics of multicomponent polymer systems, with special emphasis on polymer blends and mixtures. After a brief introduction of the relevant thermodynamic principles – laws of thermodynamics, definitions, and interrelations of thermodynamic variables and potentials – selected theories of liquid and polymer mixtures are provided: Specifically, both lattice theor...
متن کاملConfined flow of polymer blends.
The influence of confinement on the steady-state morphology of two different emulsions is investigated. The blends, made from polybutene (PB) in polydimethylsiloxane (PDMS) and polybutadiene (PBD) in PDMS, are sheared between two parallel plates, mostly with a standard gap spacing of 40 microm, in the range of shear rates at which the transition from "bulk" behavior toward "confined" behavior i...
