نویسندگان
چکیده
Cellulose is one of the most frequently used natural polymers. Some characteristics Carboxymethyl cellulose polymer have been studied, which a semi-crystalline, non-toxic material. CMC made by several methods including homogeneous Procedures and heterogeneous Procedures. It also has many applications such as its use in Pharmaceuticals Cosmetics, Drilling Fluids, Manufacture, CMC-Based Drug Delivery Systems for Wound Infections. The aim review to study polymer, know some properties, take an example mixing with another identify procedures preparation, examples part applications.

Carboxymethyl Cellulose Acetate Butyrate: A Review of the Preparations, Properties, and Applications
Carboxymethyl cellulose acetate butyrate (CMCAB) has gained increasing importance in several fields, particularly in coating technologies and pharmaceutical research. CMCAB is synthesized by esterification of CMC sodium salt with acetic and butyric anhydrides. CMCAB mixed esters are relatively high molecular weight (MW) thermoplastic polymers with high glass transition temperatures (Tg). CMCAB ...
متن کاملElectric 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...

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 کاملNi(0)-CMC-Na - nickel colloids in sodium carboxymethyl-cellulose: catalytic evaluation in hydrogenation reactions.
A recyclable catalyst, Ni(0)-CMC-Na, composed of nickel colloids dispersed in a water soluble bioorganic polymer, sodium carboxymethylcellulose (CMC-Na), was synthesized by a simple procedure from readily available reagents. The catalyst thus obtained is stable and highly active in alkene hydrogenations.
