Abstract: The present invention relates to a modified cellulose ester containing unsaturated pendant 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 cross-linking 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.
Abstract translation: 本发明涉及含有不饱和侧基的改性纤维素酯，其可以通过使含有残余羟基的纤维素酯与例如马来酸酐在乙酸溶剂中与乙酸钠催化剂反应来制备。 改性纤维素酯不是均聚的，而是在乙烯基交联剂和光引发剂的存在下在暴露于紫外线辐射下共聚。 改性纤维素酯可用作木材，金属，塑料，纸，板和其它基材的保护和/或装饰涂层，以及用于印刷油墨的添加剂和指甲油。 此外，由于侧链羧基与胺形成亲水盐的倾向，所以可以将改性纤维素酯配制成水分散性。
