Abstract:
1. A method for casting a styrenic fluoropolymer film on a substrate comprising the steps of: preparing a polymer solution by dissolving the fluoropolymer in a solvent or solvent blend whose Hansen solubility parameters (HSPs, MPa wherein R 1 , R 2 , and R 3 are each independently hydrogen atoms, alkyl groups, substituted alkyl groups, or halogens, wherein at least one of R 1 , R 2 , and R 3 is a fluorine atom, and wherein R is each independently a substituent on the styrenic ring, n is an integer from 0 to 5 representing the number of the substituents on the styrenic ring; and casting the polymer solution on a substrate.
