摘要：
Water swellable elastomer (WSE) based on thermoplastic polyether-ester elastomer (TPEE) was prepared by adding ionomer Surlyn as compatibilizer, while cross-linked sodium polyacrylate (CPNaAA) was chosen as water-absorbent resin. The effects of CPNaAA content on the water-swelling properties and mechanical properties of WSE were investigated. The effects of Surlyn content on the compatibility, mechanical properties and water absorbency of WSE were further studied. The results show that the addition of Surlyn can enhance the interfacial compatibility and interfacial adhesion between the matrix phase and water-absorbent resin phase. The particle size of CPNaAA in TPEE matrix is reduced and the dispersion of CPNaAA in matrix becomes better. Meanwhile, mechanical and water-swelling properties are improved with the low mass loss of CPNaAA particle after swelling. © 2016, Chengdu University of Science and Technology. All right reserved.
