It offers another important and versatile route to further improve the interfacial compatibility between two phases.
Zhang [26,27] reported a supertoughened PLA ternary blend with moderate strength and stiffness prepared by melt-blending of PLA with elastomeric ethylene-butyl acrylate-glycidyl methacrylate terpolymer (EBA-GMA) and zinc ionomer of ethylene-methyacrylic acid copolymer (EMAA-Zn) at 240C.
Effective interfacial compatibilization at elevated blending temperatures was thought to be responsible for the significant increase in notched impact strength.
