The Adsorption Behaviors of Thermosensitive poly(DMAAPS) Grafted onto EVA Porous Support

Abstract

The adsorption ability of poly(DMAAPS) grafted onto ethylene vinyl acetate (EVA) porous support prepared using various polymerization times was investigated at a variety of temperatures and permeated sample volumes. The permeability coefficient through Poly(DMAAPS) was also investigated. The poly(DMAAPS) was successfully grafted onto a EVA porous support through graft polymerization in water containing DMAAPS monomer with polymerization time of 4, 6 days, and 7 days. The permeability coefficient of Poly(DMAAPS) onto a EVA porous support decreased with increasing the temperature. Additionally, the adsorption amount of cation increased as permeated volume increased.
