Abstract

In order to set up a proper AKD quantification method for studing AKD hydrolysis, a quantitative analysis method using Uv/vis spectroscopy was evaluated and compared to the conventional GC-MS analysis. Hydrolysis rates of AKD emulsions during storage at 4$0^{\circ}C$ were measured by the UV/vis analysis. Owing to its simplicity and capability of measuring the unreacted AKD significantly even in a small amount, UV/vis method proved to be more suitable for studing AKD hydrolysis than GC-MS analysis. AKD hydrolysis was affected by the types of emulsifiers. Polymer stabilized AKD emulsion hydrolyzed more rapidly than starch stabilized AKD.
