摘要：
The paper deals with the preparation and application of the cationic polyurethane for paper sizing agent. The prepolymer is synthesized through the multiple bond addition reaction with the monomers of glyceryl monostearate. Then the prepolymer is extended, neutralized and emulsified. The cationic polyurethane sizing agent has the excellent properties of sizing. The main factors affecting the sizing degree are also discussed.
