Improvement of Durability of Wood by Maleic Anhydride
Wood as a natural renewable material is vulnerable to degradation by microorganisms and susceptible to change in dimension by water. In order to effectively improve the durability of wood, an active reagent, maleic anhydride (Man) was selected for wood modification. Man was first dissolved into a solvent, and then penetrated into wood porous structure under a vacuum/pressure condition. After a ...
متن کاملPhysicochemical Characterization and the Comparison of Chitin and Chitin Modified with Maleic Anhydride
Firstly, chitin was modified via ring-opening reaction with maleic anhydride in lithium chloride/ N,N-dimethylacetamide. Then, both chitin and chitin modified with maleic anhydride (CMA) were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) method, ultraviolet-visible (UV-Vis) spectroscopy, and scanning electron microscopy (SEM). Thermogravimetric analysi...
متن کاملCarbon Nanotubes Reinforced Maleic Anhydride-Modified Xylan-g-Poly(N-isopropylacrylamide) Hydrogel with Multifunctional Properties
Introducing multifunctional groups and inorganic material imparts xylan-based hydrogels with excellent properties, such as responsiveness to pH, temperature, light, and external magnetic field. In this work, a composite hydrogel was synthesized by introducing acid treated carbon nanotubes (AT-CNTs) into the maleic anhydride modified xylan grafted with poly(N-isopropylacrylamide) (MAX-g-PNIPAM) ...
متن کاملSynthesis and Characterization of Acrylic acid Grafted Styrene- Maleic anhydride Copolymer
Modification of Styrene-maleic anhydride copolymer, synthesized in toluene using benzoyl peroxide (BPO) as initiator, through graft copolymerization of hydrophilic monomer, acrylic acid, (AAc), has been carried out in aqueous medium by chemical and gamma radiation methods. Optimum conditions pertaining to maximum percentage of grafting were evaluated as a function of different reaction paramete...
متن کاملSynthesis and uranyl ion adsorption study of cross-linked allyl propionate-maleic anhydride-styrene terpolymer
Allyl propionate-maleic anhydride-styren terpolymer has been modified with glycerin in order to prepare a new cross-linked functional polymer sorbent. The synthesized cross-linked polymer sorbent has a network structure and contains carboxylic acid, carbonyl, hydroxy, and ester groups, all of which are capable of interacting with metal ions. The sorption behavior of UO 2 ions under optimum sorp...
