Development of thermo-responsive poly(vinyl alcohol)-g-poly(N-isopropylacrylamide) copolymeric membranes for separation of isopropyl alcohol/water mixtures via pervaporation
(Elsevier Science Inc, 2016)
This study aims to develop thermo-responsive poly(N-isopropylacrylamide) (PNIPAAm) grafted poly(vinyl alcohol) (PVA-g-PNIPAAm) copolymer membranes for separation of isopropyl alcohol (IPA)/water mixtures via pervaporation. ...
Synthesis and characterization of pH- and temperature-sensitive materials based on alginate and poly(N-isopropylacrylamide/acrylic acid) for drug delivery
(Springer, 2016)
The significant developments in the field of polymer have advanced the synthesis of polymer-based materials and have expanded their use in a wide variety of applications. Today, polymers can be designed to change their ...
Synthesis and characterization of thermo/pH-sensitive pectin-graft-poly (dimethylaminoethyl methacrylate) coated magnetic nanoparticles
(ELSEVIER, 2020)
Herein, thermo- and pH-sensitive pectin-graft-poly(dimethylaminoethyl methacrylate) copolymer-coated magnetic nanoparticles were synthesized via a green and rapid synthetic approach based on microwave irradiation. Firstly, ...

(WILEY, 2020)
kappa-Carrageenan-graft-poly(dimethylaminoethyl methacrylate) (CRG-g-PDMA) was synthesized via free-radical copolymerization under microwave irradiation.C-13-Nuclear magnetic resonance spectroscopy (C-13-NMR), fourier-transform ...
Synthesis, characterization and swelling performance of a temperature/pH-sensitive kappa-carrageenan graft copolymer
(ELSEVIER, 2020)
A binary graft copolymerization of dimethylaminoethyl methacrylate (DMAEMA) and acrylic acid (AA) onto kappa-carrageenan (CG) was performed by using microwave irradiation in the presence of 4A'-Azobis(4-cyanovaleric acid) ...
Microwave-assisted synthesis of alginate-g-polyvinylpyrrolidone copolymer and its application in controlled drug release
(Springer, 2014)
The aim of this study is to synthesize graft copolymer (NaAlg-g-PVP) in microwave oven and prepare pH-responsive beads with high entrapment efficiency. For this purpose, PVP was grafted onto sodium alginate using microwave ...
pH responsive itaconic acid grafted alginate microspheres for the controlled release of nifedipine
(Elsevier Sci Ltd, 2011)
A series of pH responsive alginate-g-poly(itaconic acid) (NaAlg-g-PIA) microspheres were prepared as drug delivery matrices of nifedipine cross-linked by glutaraldehyde (GA) in the hydrochloric acid catalyst. Graft copolymers ...
Graft copolymerization of itaconic acid onto sodium alginate using benzoyl peroxide
(Elsevier Sci Ltd, 2010)
Graft copolymers of sodium alginate (NaAlg) with itaconic acid (IA) were prepared in aqueous solution using benzoyl peroxide (BPO) as the initiator. Grafted copolymers (NaAlg-g-PIA) were characterized by Fourier transform ...
Controlled release of indomethacin from crosslinked alginate beads
(Walter De Gruyter Gmbh, 2008)
Beads of the sodium alginate ( NaAlg) were prepared by dropping aqueous sodium alginate ( NaAlg) into glutaraldehyde ( GA) as a crosslinker and HCl as a catalyst mixture solution. Beads prepared were used to deliver a model ...
