Study on Modification of Esterified Corn Starch Emulsion

Modification of esterified corn starch emulsion was made by copolymerization of it with car-boxylic butadiene-acrylonitrile latex,and the suitable reaction conditions were obtained through orthogonal -izing experiments. The dry bond strength and wet bond strength of the copolymerized emulsion reached 9.865MPa and 1.032MPa respectively. So, the copolymerized emulsion could be used as main agent of a new type of API.
