Grafting Copolymerization of (Sodium Alginate/ Acrylic Acid/ MethacrylicAcid) by Gamma Radiation: Preparation and Characterization
نویسندگان
چکیده
Grafted copolymer (sodium alginate (Na. Alg)- acrylic acid (AcA)– methacrylic (MAcA)) was prepared by the gamma irradiation-induced copolymerization in presence of N, N-methylene bisacrylamide (MBA) as a co monomer crosslinker. The functionality, morphology and thermal stability have been examined using FTIR spectroscopy, SEM, TGA-DTA, respectively. surface grafted shows smooth relatively homogeneous appearance. Thermogravimetric analysis good suitable for all domain practical application which this polymer is used till near 400°C effect preparation conditions on swelling property has investigated mechanism graft through irradiation process also discussed. obtained results revealed that optimum preparing were 20% Acrylic acid, 10% Methacrylic 0.4 wt % sodium at dose 15 KGy with addition 0.03 MBA

Spherical microparticles, capable of responding to magnetic fields, were prepared by encapsulating dextran-coated Fe3O4 nanoparticles into chitosan poly(acrylic acid) (PAA) microspheres template. The obtained magnetic microspheres were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray powder diffra...
متن کاملNanometric grafting of poly (N-isopropylacrylamide) onto polystyrene film by different doses of gamma radiation
Poly N-isopropylacrylamide was successfully grafted onto a polystyrene cell culture dish by gamma ray. In this study, the effect of a radiation dose (radiation absorbed dosages of 10, 20, 30, 40 KGy) under appropriate temperature and grafting conditions was investigated. The FTIR analysis showed the existence of the graft PNIPAAm on the substrate. The optimal value of the dose for grafting was ...

متن کاملPreparation of Poly(acrylic acid) Hydrogel by Radiation Crosslinking and Its Application for Mucoadhesives
A mucoadhesive drug delivery system can improve the effectiveness of a drug by maintaining the drug concentration and allowing targeting and localization of the drug at a specific site. Acrylic-based hydrogels have been used extensively as a mucoadhesive system owing to their flexibility and excellent bioadhesion. In this experiment, poly(acrylic acid) was selected to prepare the bioadhesive hy...
متن کاملKinetics of Copolymerization of PEG-Containing Multiacrylates with Acrylic Acid
The compositional dependence of the polymerization kinetics of multiacrylate copolymers with acrylic acid (AA) was examined. The multiacrylates considered were dior triacrylate esters of oligo(ethylene glycol) (OEG). The multiacrylate polymerization rate increased with the OEG chain length in the absence of added AA. This monomer size dependence was due to mobility-related effects on the pendan...
