The present invention relates to a process for producing composite materials which consist essentially of a) at least one oxidic phase and b) at least one organic polymer phase, by copolymerizing - at least one compound A selected from aryloxy metallates, aryloxy semimetallates and aryloxy esters of non-metals which form oxo acids and are different from carbon and nitrogen, with - at least one compound B selected from formaldehyde and formaldehyde equivalents, in a reaction medium which is essentially anhydrous, the compound B being used in an amount such that the molar ratio of formaldehyde to the aryloxy groups in the compound A is at least 0.9:1. |
