摘要

•Reactive extruder with twice initiations function was designed and applied for starch modification.•Starch-based SAP was fabricated by REX using CAN (firstly) and APS (secondly) as initiators.•Both graft efficiency and reaction efficiency increased significantly after the second initiation.•Water absorption capacity of the polymers increased by about 23.36% after adding APS.
