ABSTRACT:
The morphology of a polymer alloy displaying miscibility over some region of composition and temperature may be varied by thermodynamically altering the miscibility, such as raising the temperature for an LCST system, to phase separate the components then quenching the alloy below the glass transition temperature of the matrix phase. Such phase separated alloys have improved toughness.
