| Abstract: | The cationic polyaminamide was synthesized by melting employing adipic acid,diethy lenetriamine,epichlorohydrin and urea as staring materials.The influences of reaction time and temperature on the apparent viscosity of the product was studied.The apparent viscosity of product produced by amidation reaction at 170 ℃ for 150 min,produced by deamination reaction at 125 ℃ for 8 h and produced by crosslinking reaction at 70 ℃ for 70 min was 892,370 and 480 mPa·s,respectively.The pH value of the product was 57,and the solid content of the product was(66±1)%,and the number average molecular weight of product was 15 500 by freezing-point depression.The structure of the product was characterized by IR spectrum.Solid content and the apparent viscosity of the product was improved,compared with the commercial product. |
