ABSTRACT:
The present invention is a germanium compound having the following general formula I: ##STR1## in which n is a positive integer less than 50 when the general formula is linear and is between 3 and 50 when the general formula is cyclic, and preferably between 3 and 6, and the R radicals, which are identical or different, are chosen independently from hydrocarbyl radicals, or, the R radicals form a hydrocarbon chain optionally containing one or two heteroatoms, optionally substituted by one or more C.sub.1 -C.sub.3 alkyl radicals, which are optionally unsaturated, the compound of general formula I being, when it is linear, terminated by two radicals R.sub.3 Ge-- and R.sub.3 Ge--O-- respectively, provided that the different R radicals cannot simultaneously correspond to a methyl radical and when the general formula I is cyclic, the two radicals attach to the same germanium atom, cannot correspond to a divalent chain of the formula: ##STR2## Z.sub.1 and Z.sub.2 being chosen from methyl radicals or hydrogen atoms.
