摘要： A dielectric polymeric composition comprising a polymeric matrix comprising structural units derived from a polymerizable vinyl monomer; an ionic liquid comprising an organic cation and a balancing anion, wherein the ionic liquid is miscible or partially miscible with the polymerizable vinyl monomer, and wherein the concentration of ionic liquid in dielectric polymeric composition ranges from 0.5 to 30 wt. %; and less than 10 ppm of unreacted polymerizable vinyl monomer, based on the total weight of the composition, wherein an amount of unreacted polymerizable vinyl monomer in the composition is measured via HPLC. The polymeric matrix further comprises structural units derived from a polymerizable co-monomer comprising a functional group that has the ability to form hydrogen bonds within the polymeric matrix. The polymeric matrix further comprises a crosslinking agent, and wherein the polymeric matrix comprises covalent crosslinks between the crosslinking agent and the structural units derived from the polymerizable vinyl monomer.

摘要： A composition for removing a cosmetic material from a substrate includes glycerin ethoxylate and linear alkyl benzene sulfonate (LABS). An application of the composition to a stain including a deposit of a cosmetic material at a white polyester-cotton blend fabric to provide a stained polyester-cotton blend fabric exhibits an increased stain removal measured as reflectance observed at 460 nm by at least about 35% compared to a reflectance observed at the stained polyester-cotton blend fabric prior to the application. A treatment including the composition applied to the stained polyester-cotton blend fabric provides a reflectance at the stained polyester-cotton blend fabric that is greater than a reflectance observed at a white polyester-cotton blend fabric stained with a deposit of a cosmetic material and that has been treated with either the glycerin ethoxylate alone or that has been treated with the linear alkyl benzene sulfonate alone.
