| Abstract: | Through two-step copolymerization using N, N-Dimethyl-l,3-propanediamine, urea, 1,4-dichlorobutane as raw materials, a new primary-chain water-soluble quaternary ammonium polymers was synthesized. The relationship between dosage of raw materials, reaction temperature, reaction time and rate of conversion was studies by orthogonal experiments. The optimum conditions were ascertained as follow： the molar ratio of N, N-dimethyl-l,3-propanediamine to urea is 2 ： 1; the reaction temperature is 135~C; time is 11 h, the conversion of the intermediate was as high as 99%; and then the molar ratio of the intermediate to 1,4-dichlorobutane is 1 ： l; the reaction temperature is 90℃; time is 6 h. The title polymers were characterized by FTIR, HNMR, thermoanalyses and intrinsic viscosity. |
