Patent ID: 7361706

Claim:
A process for preparing a water- and oil-repellent, antistatic composition comprising the steps of (a) combining (i) at least one nonpolymeric ionic salt consisting of at least one cation and at least one anion, said cation being selected from the group consisting of monovalent metal cations, divalent metal cations, and organic onium cations, and said anion being a weakly coordinating anion, the conjugate acid of said anion having an acidity greater than or equal to that of a hydrocarbon sulfonic acid, and with the proviso that said anion is organic or fluoroorganic when said cation is a metal, (ii) at least one fluorochemical repellent, and (iii) at least one thermoplastic polymer; and (b) melt processing a combination of (iii) and at least one of (i) and (ii).
