摘要： The invention relates to concentrated solutions of mixed alkaline-earth alkoxide compounds M(OCH
2 R
6 )
2-x (OR
7 )
x and an aluminum compound AI(OCH
2 R
6 )
3-y (OR
7 )
y in aprotic solvents, wherein: M is an alkaline-earth metal selected from among Mg, Ca, Ba, Sr; OCH
2 R
6 is an alkoxide group comprising at least 3 and at most 40 C atoms and having a branch at the 2-position relative to the O- function, in other words R
6 = -CHR
8 R
9 , wherein R
8 , R
9 = alkyl groups C
1 - C
18 independently of each other; R
7 is an alkyl group having 2-15 C atoms that is either linear or has a branch ≥ the 3-position; and the sum of x and y is a number between 0.01 and 0.8, preferably 0.02 and 0.3, and especially preferably 0.03 and 0.2.
