Abstract
The mixture of polyisopirene(PI) and Sodium-2-diethylhexyl sulfosuccinate(AOT) /Decane/water microemulsion(ME) at AOT to water molar ratio (X=30) and droplet mass fraction (mf=0.08) was studied with dynamic light scattering and small angle X-ray scattering(SAXS). The light scattering was used to obtain; the diffusion coefficient of Brownian motion of the nano-droplets at different polymer concentrations and molecular weight (1000 and 4700) in the ME. The dynamics of the nano-droplets decreased with the increase of molecular weight (from 1000 to 4700) and concentration (from 0.01 to 0.09) of PI. The study of the structure by SAXS showed that with increase of PI(M.W.=1000) mass fraction from 0.01 to 0.09 at ME the size of the droplets change from 4.5 to 4.3nm and with increase of PI(M.W.=47000) concentration at ME the size of droplets change from 4.8 to 4.4nm. The size ratio of droplets to polymer decreased with increase of concentration and molecular weight of polymer and also the interaction between the droplets increased with increase of polymer concentration.
