of two or more different semi-crystalline polymers that are miscible in the crystalline state as well as in the molten state.
- Such a blend exhibits a single, composition-dependent glass-transition temperature,
and a single, composition-dependent melting point,
- This behaviour is extremely rare; very few cases are known.
