摘要： The invention concerns solutions of alkoxides containing titanium and/or zirconium and/or hafnium and magnesium and/or calcium and/or strontium and/or barium of general formula (I): [MII(OR)¿2-y(OR?1)y]n.[MIV(OR1)4-z(OR)z], in which: MII means magnesium and/or calcium and/or strontium and/or barium; MIV means titanium and/or zirconium and/or hafnium; R is an alkyl group with 1 to 18 carbon atoms; R1 is an alkyl group with 1 to 18 carbon atoms, y has a value of between 0 and 2; z has a value of between 0 and 4; and n is a number between 0.001 and 3, with the exception that n cannot be 1 when y is 2 and z is 0, or when y is 0 and z is 4. The invention further concerns the production of these alkoxides and their use.
