 If one Tg is exhibited then it will be between the Tg of the components and the resultant Tg will likely be described by a relationship such as the Flory-Fox or Kwei equations.If one of the components is semi-crystalline then the complexity of a pure crystalline phase and either one or two amorphous phases will result.If both components are semi-crystalline then the morphology will be complex since both crystal phases will likely form separately, though with influence on each other.
