摘要:

采用胶束聚合制备了一种新型的疏水缔合聚合物AM—M—BAAC/AM,其侧链含有长达18个碳原子的疏水基,研究了该聚合物的溶液性质。结果表明:该共聚物水溶液比浓粘度在20~65℃范围内变化较小;溶液临界浓度表现明显,在不同的聚合物浓度下都表现出盐增粘效应,但在较低的聚合物浓度下,盐增粘效应更为明显;对同一聚合物样品,不同盐溶液中的增稠行为表现是MgCl2>CaCl2>NaCl;论文以Huggins常数为量度还对不同的盐、不同盐浓度对溶液大分子之间的相互作用的影响作了初步的探讨。

Abstract:

A new type of hydrophobic association polymer AM-M-BACC/AM was prepared by micellar polymerization, which has a long hydrophobic group up to 18 carbon atoms, and its solution properties were studied. Results show that the reduced viscosity of aqueous solution of the copolymer has little change in the range of 20~60℃,and the critical concentration of this solution is very obvious. The viscosity increases with salt concentration under various polymer concentrations, but it raises more under the condition of lower of lower polymer concentrations. The order of the increments of the reduced viscosity for different salt is: MgCl2>CaCl2>NaCl. In addition, the influence of the type and concentration of salt on the interaction of macromolecules in solution has been investigated preliminarily on the basis of Huggins constant.
