Carboxy methyl cellulose CMC

Another binary mixture, namely, (acrylic acid/ acrylamide) was grafted onto carboxy methyl cellulose (CMC) [25]. [Pg.504]

Carrington et al. [1.124] usd thermomechanical analysis (TMA) to study the ice-crystallization temperature of 30 % (w/w) fructose, sucrose and glucose with and without sodium carboxy methyl cellulose (CMC). TMA has been used to measure the expansion of... [Pg.53]

Classical model fluids of this type are aqueous solutions of carboxy-methyl-cellulose (CMC), polyacrylamide (PAA), Carbopol (acidic polymers of acrylic acid of Goodrich), and so on. [Pg.67]

Some polysaccharides, like pullulan, can be precipitated selectively in plates with ethanol (8). Polyanionic polysaccharides like pectin or carboxy methyl cellulose (CMC) can be precipitated with cetylammonium salts (9, 10). Degradation zones in these plates will not turn opaque upon addition of the precipitant thus revealing the activity of polysaccharases. [Pg.240]

Cork powder (50—100 g L ) and sodium silicate (10—15 g L ) are generally used for the mould coat, although oflier components are sometimes included, too, e.g., carboxy methyl cellulose (CMC). The cork suspension is sprayed onto the mould surface and heated to 80—90 °C. During casting, the cork powder gradually bums away, and a new coating is usually applied once or twice a shift. [Pg.208]

Comparing with glycerol-plasticized thermoplastic pea starch (TPS)/carboxy-methyl cellulose (CMC) and TPS/microcrystaUine cellulose (MC) composites [226], scanning electron microscope (SEM) showed that there was good adhesion... [Pg.140]

Semi-synthetic polymers Chemically modifled natural polymers are classifled as semi-synthetic polymers. Some examples are epoxidised natural rubber (ENR), chlorinated natural rubber (Chlororub), nitrocellulose, carboxy methyl cellulose (CMC) and cellulose acetate. [Pg.3]

If alkaline cellulose is converted with chloroacetic acid, then the sodium salt of carboxy methyl cellulose (CMC) is obtained ... [Pg.1096]

Friction studies were carried out with a hip-joint simulator by Scholes et al. They compared the friction behavior between a number of implant materials using both carboxy methyl cellulose (CMC) solutions and biological fluids as lubricants. They found that friction coefficient for alumina/alumina was higher for biological fluids than for CMC, and attributed this to the inhibition of fluid-film formation by a protein film on the surfaces. For metal/ metal joints, the friction coefficients were lower in biological fluids, leading to the conclusion that the formation of a protein film assisted boundary lubrication. [Pg.413]

Carboxy methyl cellulose (CMC) and guar gum that both find use in the paper industry. [Pg.139]

Additives are, for example, carboxy methyl cellulose (CMC), flow modifiers, pH-controlling chemicals, preservatives (biocides), defoamers, deaeraters, dyes and... [Pg.360]

Pharmacutical formulations. Carboxy methyl cellulose (CMC), hydroxypropyl cellulose (HPC) and methyl hydroxypropyl cellulose (MHPC) are commonly used ingredients in tablet formulations of pharmaceuticals. They can either be used as one... [Pg.253]

Carboxy methyl cellulose (CMC) A synthetic gum manufactured by reacting monochloroacetate with alkali cellulose. It dissolves both in cold and hot water. It is used in bakery goods (0.05%-0.5%) to improve texture, retain moisture, improve freeze-thaw stability, and lower starch retrogradation. [Pg.675]

Stationary phase In order to prepare chiral stationary phase, 10 g of -cyclodextrin (/3-CD) and 5 g of silica gel H were weighed and dried at 110 C in an oven under vacuum for 12 h. /3-CD was dissolved in approximately 120 ml of anhydrous dimethylformamide (DMF) with a small amount of sodium the mixture was stirred for 2-3 h at 90" C and filtered. Silica gel H and 2.5 g of KH-560 (3-glycidoxypropyltrimethoxysilane) were added to the filtrate and the mixture was stirred for 12-18 h at 90" C. The suspension was filtered and washed with DMF, toluene, methanol, water, again with methanol, and then dried in air. To 2 g of obtained /3-CD-bonded silica gel, 6 ml of 0.3% aqueous solution of carboxy-methyl cellulose (CMC) sodium were added, and the slurry obtained was spread as a layer 0.2-0.4 mm thickness on glass plates 2.5 x 7.5 cm in size. Plates were dried in air and activated before use in an oven at 80°C for 1 h. [Pg.359]
