| Abstract: | The solubilities and viscosities of four novel symmetric tri-n-alkyltin fluorides in various organic solvents were studied. It is shown that these compounds do behave as transient polymers. Increasing the length of the n-alkyl chain beyond n-butyl imparts considerable solubility to this class of associative polymers and offers no steric hindrance to polymer chain formation. The effects of concentration, solvent type, temperature, and brine on the solution viscosities were also studied. These associative polymers effectively viscosify compressed gases (having liquid-like densities), such as propane and n-butane. They can therefore be used in enhanced oil recovery operations as well as in fracturing of oil wells. |
