isomorphic polymer blend
polymer blend of two or more different semi-crystalline polymers that are miscible in the crystalline state as well as in the molten state.
  1. Such a blend exhibits a single, composition-dependent @G02641@, Tg, and a single, composition-dependent @M03821@ point, Tm.
  2. This behaviour is extremely rare; very few cases are known.
