New Functional Monomer Synthesis And Polymerization Behavior Research

Along with the application and development of EOR, the research and development of floodingpolymer is becoming an important part in oilfield chemistry field. In this paper, based on the structureand the function mechanism of each new flooding polymer, three new kinds of compounds named(9-Carboxy-nonyl)–dimethyl-[2-(2-methyl-acryloyloxy)-ethyl]-ammonium bromide, 10- Acryloyloxy-decanoic acid and Decatal- dimethyl- [2-(2-methyl-acryloyloxy)-ethyl]-ammonium bromide weredesigned and synthesized. Each of these three kinds of compounds as the functional monomers reactedwith AM respectively. Three kinds of new copolymers named zwitterionic-comb-like polyacrylamide,comb-like polyacrylamide and cation-hydrophobical-associating polyacrylamide were synthesized.Copolymerization was initiated by a multi-initiating system of ammonium persulfate,sodiumformaldehydesulfoxylate and AIBN. Concentrating the structure characteristics of two kinds of goodpolymers into one kind of polymer is the main idea in research.The synthetic method of the three new kinds of compounds were confirmed in this paper andtheir optimum synthetic conditions were confirmed too.The three new kinds of compounds werecharacterized by means of 1H-NMR,FT-IR,qualitatire titration and melting points. The syntheticmethod of the three new kinds of copolymers was confirmed in this paper and their optimum syntheticconditions were confirmed too. Some copolymers were synthesized by FT-IR.
