Inverse gas chromatography (IGC) is a very fast, accurate, and reliable technique to measure diffusion coefficients. This technique however, has been limited to measurements in the infinite dilution region, i.e., in the region of negligible amount of solvent in the polymer. We have extended the scop
Partial esterification of cellulose using acyl chlorides having 5 and 16 carbon atoms was performed in a swelling medium to produce cellulosic esters with two different degrees of substitution (DS Γ 0.15 and 0.45). The effects of this treatment on the surface energy, on the water uptake, and on the
Three polypyrrole-silica nanocomposites were characterized by inverse gas chromatography (IGC) at 60 and 80degreesC using both linear and branched alkane probes. The IGC data for these materials were compared with those obtained for the ultrafine silica sol and polypyrrole (PPy) bulk powder referenc
