A flowable crosslink polymer blend was successfully developed through a reactive compounding process. An epoxy captained ethylene acrylate copolymer and a carboxylic acid and zinc ion contained ethylene acrylic copolymer were employed to react in a twin screw extruder to form a partially crosslink polymer blend which was flowable at high temperature due to the rapid transesterification catalyzed by the zinc ion in the polymer. The developed crosslink polymer blend showed a significant improvement of the mechanical strength, thermal stability, and fatigue performance compared to the neat ethylene acrylic copolymer because of the strong chemical crosslink among polymer chains. © 2017 Wiley Periodicals, Inc.
