Patent ID: 7329702

Claim:
A method of making a composition, the method comprising: combining components comprising: a first layered silicate having a first d-layer spacing, and a block copolymer having: at least one block is compatible with the first layered silicate, and at least one highly fluorinated block that is prepared from a fluorinated acrylate monomer described by the formula: H 2 C═C(R 2 )C(O)O—X—N(R)SO 2 R f ′ wherein: R f ′ is —C 6 F 13 , —C 4 F 9 , or —C 3 F 7 ; R is hydrogen, C 1 to C 10 alkyl, or C 6 -C 10 aryl; and X is a divalent connecting group; applying at least sufficient thermal energy and at a sufficient shear rate to provide a mixture comprising the block copolymer having dispersed therein at least one of: a) a second layered silicate having a second d-layer spacing that is greater than the first d-layer spacing; or b) exfoliated silicate platelets.
