Synthesis and optimization of poly (HEMA-co-EGDMA-co-VBC) for preparation of hypercrosslinked aminated polymer using DoE method

Hydrophilic quarternary ammonium resin (HQAR) was successfully derived from hypercrosslinked Poly(HEMA-co-EGDMA-co-VBC) polymer. The objective of this project is to develop HQAR via three stages, precursor synthesis (suspension polymerization), hypercrosslinking reaction, and functionalization react...
