Abstract:

Polyvinylidene fluoride (PVDF) resin was used as the substrate, and grafted with ethyl styrenesulfo- nate (ETSS) monomer through pre-irradiation graft polymerization method. The influence of absorbed dose, grafting temperature, reaction time, and concentration of ETSS monomer on grafting yield (Rg) were investigated. After that, the PVDF-g-PSSA ion exchange resin was obtained via hydrolysis of PVDF-g-PETSS at 95 oC. The grafting of ETSS and preparation of PVDF-g-PSSA were proved by FTIR, XPS and TGA. At the Rg of 120%, the ion exchange capacity of PVDF-g-PSSA reached 2.05 mmol/g. This work provides a facile route for the preparation of ion exchange resin.
