isomorphic polymer blend

https://doi.org/10.1351/goldbook.IT07233
Polymer blend of two or more different semi-crystalline polymers that are miscible in the crystalline state as well as in the molten state.
Notes:
  1. Such a blend exhibits a single, composition-dependent glass-transition temperature, \(T_{\rm{g}}\), and a single, composition-dependent melting point, \(T_{\rm{m}}\).
  2. This behaviour is extremely rare; very few cases are known.
