SYNTHESIS AND CHARACTERIZATION OF A NOVEL FLUORINE-CONTAINING HYDROPHOBICALLY ASSOCIATING POLYMER*

Received Date: 23 February 1998

In this article, the synthesis and characterization of a novel fluoromonomer and its copolymer withacrylamide is reported. 2 -perfluoroamyl -4- hydroxylquinoline 2 was synthesized from ethyl 2, 2 -dihydro-perfluoroheptanoate in high yields. The monomer 4 was then synthesized from 2 in two steps readily in highyields. Synthesis and characterization of copolymers of acrylamide (AM) and the fluoromonomer wereinvestigated. The composition and intrinsic viscosity of these copolymers were studied. It was found that the rheological properties of aqueous solutions of polyacrylamide were modified significantly when a small proportion of the fluoromonomer 4 was incorporated on investigating the viscosity-concentration profiles,pseudoplasticity of these solutions and the effect of the presence of surfactant.These results could be explained by the hydrophobic association of the fluorocarbon segments in the aqueous solutions of these copolymers.
