Preferred Label : homogeneous polymer blend;
IUPAC definition : Polymer blend that is a single-phase structure.;
Scope note : for a polymer blend to be miscible it must obey the thermodynamic criteria of miscibility.; modified from previous definition. the definition proposed here is preferred because
it emphasizes the requirement for homogeneity over miscibility.; miscibility is sometimes assigned erroneously on the basis that a blend exhibits a
single tg or is optically clear.; the miscible system can be thermodynamically stable or metastable.; for components of chain structures that would be expected to be miscible, miscibility
may not occur if molecular architecture is changed, e.g., by crosslinking.;
