Synthesis and application of cross-linked graft copolymer from poly(vinyl alcohol) and malic acid
نویسندگان
چکیده
A novel polymeric sorbent has been synthesized by graft copolymerization of crosslinked polyvinyl alcohol with malic acid, and characterized by FTIR, TGA and swelling studies. A suitable and interesting method has been developed for the extraction and separation of lead ion with the graft copolymer. The lead ion uptake capacity of the polymer has been evaluated vis-a-vis varying pH and metal ion concentration. Pb(II) ion has been isolated quantitatively from various synthetic mixture containing metal ions (Cd(II), Zn(II), Ni(II), Hg(II)) commonly found in battery and electroplating waste. The synthesized material has also been tested for analyzing real samples such as solder, lead concentrate and electroplating waste.

Synthesis of pH Sensitive Hydrogels Based on Poly Vinyl Alcohol and Poly Acrylic Acid
In this research, hydrogels based on poly vinyl alcohol and poly acrylic acid blend were prepared which were cross-linked by applied thermal conditions. Afterward, effects of time and heating on water uptake were investigated. The highest water uptake value exhibited by the sample that was heated for 20 min. at 110 ºC was about 2129% after 4 days at equilibrium state. Hydrogels exhibited p...
متن کاملSynthesis and Characterization of Poly(ethylene-co-vinyl alcohol)-graft-poly(ε-caprolactone)
Graft poly(ε-caprolactone)s (PCLs) with high graft density were synthesized by using random copolymer poly(ethylene-co-vinyl alcohol) (EVOH) to initiate ring-opening polymerization of ε-caprolactone, with and without cocatalyst Sn(Oct)2. The graft copolymer were characterized by IR, 1H and 13C NMR. The solution property and the crystallization behavior were also investigated.

Graft polymerizations of vinyl acetate onto granular corn starch were initiated by cobalt-60 irradiation of starch-monomer-water mixtures. and ungrafted poly(vinyl acetate) was separated from the graft copolymer by benzene extraction. Conversions of monomer to polymer were quantitative at a radiation dose of 1.0 IvIrad. However, over half of the polymer was present as ungrafted poly(vinyl aceta...

The post-functionalization of poly(3-hexylthiophene) (P3HT) via various synthetic routes is reported. Well-defined and monofunctionalized ω-thiol-terminated P3HT, ω-carboxylic acid-terminated P3HT, ω-acrylate-terminated P3HT, and ω-methacrylate-terminated P3HT are obtained in high yields through a straightforward procedure. From those, different novel P3HT-based graft copolymers are synthesized...
