Synthesis and characterization of temperature and pH responsive Poly(N-isopropylacrylamide) copolymer
Temperature responsive poly(N-isopropylacrylamide) (PNIPAM) exhibits a lower critical solution temperature (LCST) of approximately 32 °C in aqueous solution, below which the polymer is water soluble and above which it becomes water insoluble. The LCST of PNIPAM copolymer increases responding to hydrophilic block acrylic acid (AA). The copolymer is pH and temperature responsive. The duel respons...
متن کاملTemperature-responsive self-assembly of charged and uncharged hydroxyethylcellulose-graft-poly(N-isopropylacrylamide) copolymer in aqueous solution
Temperature-induced interchain association and contraction of species in aqueous solutions of charged (MHEC(-)-g-PNIPAAM) and uncharged (MHEC-g-PNIPAAM) modified hydroxyethylcellulose-graft-poly(N-isopropylacrylamide) copolymer have been studied with the aid of turbidimetry and dynamic light scattering (DLS). It was shown that by attaching PNIPAAM chains to the backbone of a hydrophilic cellulo...
متن کاملSynthesis and characterization of a novel temperature-pH responsive copolymer of 2-hydroxypropyl acrylate and aminoethyl methacrylate hydrochloric salt
In this investigation, a novel temperature-pH responsive copolymer was prepared by the radical copolymerization between 2-hydroxypropyl acrylate (HPA) and aminoethyl methacrylate hydrochloric salt (AMHS). The molecular structure of the corresponding copolymer has been confirmed by 1H NMR and FTIR measurements. The results indicated that the lower critical solution temperature (LCST) of the resu...
متن کاملPreparation and characterization of the graft copolymer of chitosan with poly[rosin-(2-acryloyloxy)ethyl ester].
Graft copolymerization of rosin-(2-acryloyloxy)ethyl ester (RAEE) onto chitosan (Cts) was carried out under microwave irradiation using potassium persulfate as an initiator. The structures, morphology, and thermal properties of the Cts graft copolymer (Cts-g-PRAEE) were characterized by means of FT-IR, XRD, SEM, and TG. Also, Cts and Cts-g-PRAEE copolymer were used as carriers of fenoprofen cal...
