The melt viscosity (,Ta) is calculated for polydisperse branched polymers by two methods: (1) by extending Graessley's theory of melt flow of polydisperse linear chains to include the effects of branching, and (2) by empirical deduction leading to the relation (~TB;'/('/L)= [(Ss:)w/ (SL2)~,] w2 for
## Abstract A technique is described for performing phase boundary calculations (cloudβpoint calculations) for solutions of a polydisperse polymer in a solvent component. The polymer is characterized as a potentially large number of individual components. The technique employs the Newton method for
We report a study of the creaming behavior of an alkane-inwater emulsion at varying oil volume fractions in the presence of the nonadsorbing polymer, hydroxyethylcellulose (HEC). Pairwise interaction potentials predict a shallow secondary minimum for this system arising from the attractive potential
## Abstract Polydisperse systems of polymer liquid crystal (PLC) macromolecules consisting of LC and flexible sequences are considered, particularly at the phase transition LCβi from an anisotropic to the isotropic phase. The Flory and Matheson lattice model is used for formulation of the partition
