Method for dispersing miscible polymeric components

摘要

A method for dispersing a second polymer within a first polymer is disclosed, the polymers being mutually miscible and when blended exhibit lower critical solution temperature (LCST) type behavior. The first and second polymers are blended together at a temperature for easy processing and then phase separated at a temperature above the LCST of the blended polymer pair. The phase separated polymers are then cooled to a temperature wherein the polymer pair become fixed in the phase separated state.
