Electric Properties of Carboxymethyl Cellulose
Carboxymethyl cellulose [C6H7O(OH)3x(OCH2COOH)x]n is a derivative of the regenerated cellulose [C6H10O5]n with hydroxy-acetic acid (hydroxy ethanoic acid) CH2(OH)COOH or sodium monochloroacetate ClCH2COONa. The CMC backbone consist of D-glucose residues linked by -1,4-linkage. The molecular mass of one glucose unit in CMC chain is mCMC = 146.14 + 75.04x, where x 3 is the degree of substitu...
متن کاملSynthesis, Characterisation and Flocculation Properties of Carboxymethyl Cellulose-g Acrylamide
Graft copolymers of acrylamide on carboxymethyl cellulose (d.s 0.4-0.5) were prepared by the use of ceric ion, ceric ion/reductant molecule initiator systems in aqueous medium. The graft copolymers were characterized by IR spectroscopy. The extent of graft copolymerisation was measured in terms of grafted chains as a function of both ceric ion and ceric ion/reductant molecule concentrations. It...
متن کاملKINETICS AND MECHANISM OF GRAFT POLYMERIZATION OF ACRYLONITRILE ONTO STARCH INITIATED WITH POTASSIUM PERSULFATE
A new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. In this study potassium persulfate system was used for initiation the polymerization. Graft polymerization of acrylonitrile (AN) onto starch (Sta) was carried out in aqueous solution using potassium persulfate (I) redox system. It was found that the percentage of grafting and rate of gr...
متن کاملPhysical, Mechanical, and Antimicrobial Properties of Carboxymethyl Cellulose Edible Films Activated with Artemisia sieberi Essential Oil
Background: Edible films and coatings are biodegradable that can preserve the quality and extend the shelf life of foods. The aim of this study was to investigate the physical and mechanical properties, and antimicrobial activity of carboxymethyl cellulose (CMC) film containing Artemisia sieberi Essential Oil (AEO). Methods: The studied parameters were the antibacterial activity and physical p...
