摘要 |
<p>The present invention relates to a grafted cellulose ester prepared by reacting a cellulose ester containing residual hydroxyl groups with an acrylic based compound and m-isopropenyl- alpha , alpha '-dimethylbenzyl isocyanate. The grafted cellulose ester is a urethane-containing product having pendant (meth)acrylate and alpha -methylstyrene moieties. The grafted cellulose ester is readily self-polymerizable in the presence of a photoinitiator upon exposure to ultraviolet radiation. It does not require the presence of vinyl monomers to become crosslinked. The grafted cellulose ester is useful as a protective/decorative coating for wood, metal, plastics, and other substrates.</p> |
