Solvent and polymer interactions

In polymer solutions and blends, it becomes of interest to understand how the surface tension depends on the molecular weight (or number of repeat units, IV) of the macromolecule and on the polymer-solvent interactions through the interaction parameter, x- In terms of a Hory lattice model, x is given by the polymer and solvent interactions through... 

A chemical is a solvent for another material if the molecules of the two are compatible and together produce a more stable system than the two materials separately. An understanding of polymer and solvent interactions can help... 

The larger the difference between polymer and solvent interaction parameters, the smaller the chanceof polymer pseudo-solution foimation. A collection of solvents, solubility parameters, and polymer solubility parameters for polymers covered by this book are given in Table 8.
