A waterborne polyureth,ane emulsion with cyano group （ --CN ）was prepared by using polypropylene glycol, polycaprolaetone, polycarbonate diol, the self-made polymeric glycol with cyano group as soft segment, isophorone diisocyanate as hard segment. The structure of the polyurethane film was characterized by infrared speclrum. The particle size and its distribution were determined by dynamic light scattering（ DLS ）. Furthermore, the influences of cyano group content on the adhesion of polyurethane film was investigated.
