POLYMER BLENDS COMPATIBILIZED WITH REACTIVE POLYMERS EXTENDED WITH MISCIBLE NONREACTIVE POLYMERS

摘要

Thermoplastic polymer blends containing normally incompatible polymers are prepared by incorporating into one polymer repeating units containing pendant cyclic iminoether groups to form a first reactive polymer and into another polymer repeating units having coreactive groups to form a second reactive polymer which is capable of reacting with said first reactive polymer tof orm linkages between the polymers wherein said blend is characterized by said first and/or second reactive polymer being blended or extended with miscible polymer(s) to form a reactive blend thereof.
