Research on Performance of Microemulsion Copolymerization Nanoparticles
(0) In EOR the fundamental demand for the polymeric solution system is temperature tolerance, salt-resisting,shearing resistance and viscosity unchanged. The inverse microemulsion polymerization and crosslinking acrylamide are developed, selecting isoparaffin and surfactants (SPAN-80, TWEEN-60) as oil phase, selecting aqueous solution ofacrylamid (AM), acrylic acid(AA), N-vinyl pyrrolidine(NVP) and crosslinking monomers as water phase to form the inverse microemulsion polymerization system(W/O). Selecting adequate crosslinking monomers and (NH4)2S2O8-SO2 redox system, and varying their proportions of crosslinking monomers and NVP,a series of crosslinked polymers of degree of hydrolysis 20％ are produced in inverse microemulsion polymerization system. Using the infrared spectrum to analyze the constitution of crosslinked polymers,according to the characteristic absorption peak of functional group we can fred that the crosslinked polymers are composed of acrylamid (AM), acrylic acid(AA) and N-vinyl pyrrolidine(NVP).
