A kind of waterborne polyurethane containing epoxy group was successfully prepared by the reaction of isophorone diisocyanate (IPDI),poly-caprolactone diol (PCL1000),triethylamine(TEA),2,2-Bis(hydroxy-methyl)propionic acid(DMPA)and 1-propanetriol glycidyl ether as the main raw materials.The structure and particle size distribution of waterborne polyurethane were characterized by Fourier transform infrared spectros-copy (FT-IR)and nano-ZS particle sizer.The FT-IR confirmed that the epoxy group had been introduced into the chain of the WPU.Moreover,the applied properties of the paper were measured as follows when the dosage of the sizing agent was 3% paper tensile strength was 51.75 N?m/g,the sizing value of paper was 35.5 s and folding endurance was 38 times.
