In particular our attention is focused on very nonpolar solvents
and solvents where extreme acidities and basicities can be realized.
Under these conditions, water must be regarded as a hot, pressurized fluid having a very low dielectric constant, thereby giving it a propensity for dissolving analytes normally extracted by nonpolar solvents
These TPUs feature good balance of resistance to fuels, oils and most nonpolar solvents
often found in industrial work environments, as well as high compressive strength, low compression set, low gas and vapor permeability and low extractability levels.
Thermodynamic interactions of poly[2-(p- chlorophenyl)-1,3-dioxolane-4-yl] methyl acrylate-co- styrene (PCKPhDMA-co-St) and poly[2-(p-chlorophenyl)-1,3-dioxolane-4-yl] methyl acrylate-co-acrylonitrile (PCKPhDMA-co-AN) with alcohols as polar and alkenes as nonpolar solvents
were investigated between 50 to 180 degC degrees by IGC.
Highly polar solvents such as alcohols and glycol ethers have low resistances, and nonpolar solvents
such as hydrocarbons have very high resistances.
