摘要

PCT No. PCT/US96/14625 Sec. 371 Date Mar. 16, 1998 Sec. 102(e) Date Mar. 16, 1998 PCT Filed Sep. 12, 1996 PCT Pub. No. WO97/11081 PCT Pub. Date Mar. 27, 1997This invention concerns modified fluorosulfonic acid compounds possessing a sulfonic acid fluoride, chloride or ester group or a sulfonic acid or a salt of a sulfonic acid group at one end and respectively a hydrolyzable or hydrolyzed silane group at the other end, said sulfonic group being adjacent a substantially fluorinated bidentate hydrocarbylene group which is in turn adjacent to a hydrocarbylenegroup linked to said hydrolyzable or hydrolyzed silane group. Self-condensation of the latter compounds provides novel siloxanes and polysiloxanes. This invention further concerns novel composites comprising a metal oxide network having incorporated therein a group having the formula: -O)qSi(OH)n-qR1mR2RfSO3Q, and compositions comprising a solid material having a reactive surface to which surface is attached at least one group having the formula: -O)qSi(OH)n-qR1mR2RfSO3Q.
