ABSTRACT:
The invention describes materials comprising organic groups containing sulphur and phosphorous bonded together by a hydrocarbon chain and bonded via phosphorous and oxygen atoms to a mineral oxide of an element M, said materials being characterized in that they comprise M-O-M′ bonds, M′representing an element of a mineral oxide identical to or different from M, in that the ratio of the element M to the phosphorous is about 0.5: 1 to about 500:1 and in that each phosphorous atom of the phosphorous-containing groups forms at least one P—O-M bond and/or P—O-M′ bond. The invention also describes a process for preparing such materials.
