Compatibility and Phase Separation of Polymer Blends

Research progress of polymer blends are reviewed,includin g compatibility and phase separation.The theory of polymer compatibility,influen ce factors on the compatibility,methods of improving and evaluating the compatib ility are elucidated.The phase separation mechanisms of polymer blends control t he properties,different morphology and sructure are formed according to the spin odal decomposition and nucleation and growth mechanism. The kinetic process for t he two phase separation mechanism is obvious different.The scatter intensity is increased exponentially with the phase separation time for the spinodal decompos ition,however,it is power\|law increase for the nucleation and growth phase sepa ration.
