Cellulose acetate hydrogen phthalate

Preproduction dye developer negatives used a combination of cellulose acetate and cellulose acetate hydrogen phthalate as barrier layers. The images produced from these negatives were outstanding in color isolation, color saturation, and overall color balance. However, solvent coating was requited with this composition, and it was not used in production.

Another major factor affecting the particle uptake is the nature of the material used to prepare the particles. Uptake of nanoparticles prepared from hydrophobic polymers seems to be higher than that from particles with more hydrophilic surfaces. Microspheres composed of polystyrene, poly(methylmethacrylate), poly(hydroxybutyrate), poly(D,L-lactide), poly(L-lactide), and poly(o,L-lactide-co-glycolide) were absorbed into the Peyer s patches of the small intestine, whereas those composed of ethyl cellulose, cellulose acetate hydrogen phthalate, and cellulose triacetate were not absorbed. Residual poly(vinyl alcohol) in the surface of PLGA nanoparticles significantly reduced the intercellular uptake, in spite of the smaller particle size." Similarly, poloxamer coating of... 

The thermal degradation of cellulose acetate hydrogen phthalate (CAP) and its blends with PMMA has been investigated by thermogravimetry [a.l75]. The TG/DTG curves showed two decomposition stages for pure CAP. The decomposition behaviour was changed with the addition of PMMA. For 90/10 and 70/30 CAP/PMMA blends, there were three...

Films of polyanihne/cellulose esters—such as acetate, propionate, acetate butyrate, and acetate hydrogen phthalate—prepared by casting solutions of N-methylpyrrolidone or formic acid were studied [145], and the effect of doping, induced by acids, on their spectral and electrochemical properties is analyzed. In this respect, the following aspects have been evidenced ...

The second approach for improving the processabihty of ICPs is to prepare their colloidal dispersions in water or an appropriate solvent The colloid dispersions of ICPs can be obtained by chemical or electrochemical oxidation of the monomer in the presence of a steric stabihzer [29-31].The key parameter for such synthesis is the choice of an appropriate steric stabihzer which adsorbs or grafts onto the polymer coUoidal particles to prevent their aggregation or precipitation. Several polymers such as polyfethylene oxide) [32], poly(vinyl pyrroHdone) [33,34], poly(vinyl alcohol) [35], ethyl hydroxy cellulose [36], poly(vinyl alcohol-co-acetate) [37], poly(vinyl methyl ether) [38,39] and block copolymer stabihzer [40] have been used as steric stabihzers to produce PPy coUoidal dispersions. Surfactants are also employed for the synthesis of ICP coUoidal dispersions [41,42]. Very recently, stable PPy dispersions were prepared by Lu et al. by polymerizing pyrrole in an aqueous medium containing different anionic salts such as sodium benzoate, potassium hydrogen phthalate, and sodium succinate [43]. These authors also reported that the conductivity of PPy dispersions was enhanced when sodium benzoate was used as dopant. Chemical oxidahve polymerization in the presence of PSS in aqueous medium produces coUoidal dispersions and improves processability [44]. CoUoidal dispersions...
