ABSTRACT:
The present invention relates to a modified cellulose ester containing unsaturated pendent groups which can be prepared by reacting a cellulose ester containing residual hydroxyl groups with, for example, maleic anhydride in acetic acid solvent with sodium acetate catalyst. The modified cellulose ester is not homopolymerizable but will copolymerize in the presence of vinyl crosslinking agents and a photoinitiator upon exposure to ultraviolet radiation. The modified cellulose ester is useful as a protective and/or decorative coating for wood, metal, plastics, paper, board, and other substrates, as well as an additive to printing inks, and as a nail polish. In addition, because of the propensity for the pendant carboxyl groups to form hydrophilic salts with amines, the modified cellulose esters can be formulated to be water-dispersible.
