Factors affecting the polycondensation of adipic acid and diethanol amine were investigated by means of orthogonal and single factor methods. The particle size, size distribution and the morphological structure of physical blowing microcapsules prepared with such a polycondensate as a dispersant were observed with optical microscope and electronic microscope, respectively. The results showed that the factors influencing the acid value of the polycondensate with different intensities during polycondensation were the temperature, time, vacuum level, and the mass of p-toluene sulfonic acid. The acid values of polycondensates suitable for dispersant in preparing physical blowing microcapsules with single-cored structure were 75.7-104.0 mg KOH/g. |
