Patent

CA 2231581

This 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 hydrocarbylene group 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)q Si(OH)n-q R1m R2R f SO3Q, and compositions comprising a solid material having a reactive surface to which surface is attached at least one group having the formula: -O)q Si(OH)n-q R1m R2R f SO3Q.

Cette invention concerne des composés d'acide fluorosulfonique modifiés possédant un groupe fluorure, chlorure ou ester d'acide sulfonique ou un acide sulfonique ou bien un sel d'un groupe d'acide sulfonique à une extrémité, et respectivement un groupe silane hydrolysable ou hydrolysé à l'autre extrémité, le groupe sulfonique étant adjacent à un groupe hydrocarbylène bidenté sensiblement fluoré, lequel à son tour est adjacent à un groupe hydrocarbylène lié audit groupe silane hydrolysable ou hydrolysé. L'autocondensation de ces derniers composés permet d'obtenir de nouveaux siloxanes et polysiloxanes. L'invention concerne également de nouveaux composites comprenant un réseau d'oxyde métallique dans lequel est incorporé un groupe de la formule -O)qSi(OH)n-qR<1>mR<2>RfSO3Q, et des compositions comprenant une matière solide présentant une surface réactive à laquelle est fixé au moins un groupe ayant la formule -O)qSi(OH)n-qR<1>mR<2>RfSO3Q.
