Synthesis of Amine-type Adsorbents with Emulsion Graft Polymerization of 4-hydroxybutyl Acrylate Glycidylether

Abstract

Radiation induced graft polymerization on polymeric matrix followed by functionalization is widely

Crosslinking induced by irradiation raises selectivity of polymeric adsorbent

“…In the case of EDA, DETA, and TETA, grafted NFs were reacted with 70% of EDA, DETA, and TETA in IPA at 60°C for 4 h, respectively. DEA modification was performed in 50% DEA/water solution at 30°C for 6 h 32,33. After modification, the adsorbents were removed from the solution, washed three times with distilled water, and dried under reduced pressure.…”

“…After modification, the adsorbents were removed from the solution, washed three times with distilled water, and dried under reduced pressure. The density of the amine group of the adsorbents was estimated as described previously 32 …”

“…To date, GMA has been successfully grafted onto all kinds of matrix polymer such as PE, PP, polyvinylidene difluoride, and others. In our previous article, we reported the graft polymerization of a new monomer 4‐hydroxybutyl acrylate glycidylether (4‐HB) which shares a similar chemical structure with GMA (Scheme ) and found 4‐HB‐grafted adsorbent showed not only better mechanical property, but also a higher adsorption capacity 32. The mechanism briefly illustrated that a subtle distinction of four methylene groups in 4‐HB made some parts in the secondary side chain longer and more flexible (Scheme ) 32.…”

The mechanism briefly illustrated that a subtle distinction of four methylene groups in 4‐HB made some parts in the secondary side chain longer and more flexible (Scheme ) 32. Considering the four methylene groups in the secondary side chain, crosslinking would be introduced into the polymer, especially into the side chain of the polymer.…”

Preparation and Characterization of Iminodiacetate Group Containing Nonwoven Polyethylene Fabrics and Its Application in Chromium Adsorption

“…A CO 2 adsorbent containing triethylamine (TEA) was prepared by radiation induced grafting of glycidyl methacrylate (GMA) onto PE-PP non-woven sheet followed by amination reaction [6]. Amine type adsorbent was synthesized from 4-hydroxybutyl acrylate glycidyl ether grafted PE/PP nonwoven fabric and used for adsorption of Cu(II), Pb(II), Zn(II), Ni(II) and Li(II) [7]. Dimethylaminoethyl methacrylate grafted PE/PP nonwoven fabric has been investigated for the removal of phosphate [8].…”
