Study on the Reaction of Cellulose with Aminoformaldehyde Resins by Thin-Layer Chromatography

Reaction of MMM and DMDHEU with cellulose was studied by a technique of thin-layer chromatography. The technique consists of spotting catalyst-contained resin solution onto cellulose-coated plate, curing at elevated temperature, and developing in a solvent system to separate unreacted resin and self-condensate from reacted portion, which remains on the initial spot. Rates of the cellulose-MMM reaction at 130, 145, and 16$0^{\circ}C$ with each of zinc acetate and zinc nitrate catalysts were determined by following change in area of spot developed on the thin plate. Activation parameters have been also calculated from the rate data.
