Abstract

Abstract: In order to study the relationship between the structure and solution property of poly(acryloyloxyethyltrimethyl ammonium chloride-acrylamide)(P(DAC-AM)), the P(DAC-AM) with cationicity of 50% and serial molecular weights were synthesized by aqueous solution polymerization, and characterized by gel permeation chromatography (GPC). Then the effects of inorganic salts on the apparent viscosity ( η a ) of P(DAC-AM) were investigated. The results showed that the value of η a increased with the increase of the molecular weight when the molecular weights of P(DAC-AM) synthesized were 1.67 × 10 6, 2.16 × 10 6 and 2.90 × 10 6 g/mol. The η a firstly decreased to the inflection point, then remained the value or increased with the increase of the salt concentration. It was discovered that the multivalent salt ions had a great effect on the η a due to the larger number of counter ions and the larger volume of the complex formed by themselves. Furthermore, the effect of anions on the η a of P(DAC-AM) was larger than that of cations. The above researches laid a foundation for the further study of the relationship among the structure, property and performance of P(DAC-AM) with serial cationicity. Graphical Abstract:
