LOW-VISCOSITY SOLUTIONS OF ALKALINE-EARTH METAL ALKOXIDES IN APROTIC SOLVENTS, METHOD FOR THE PRODUCTION OF SAME AND USE FOR THE PRODUCTION OF ZIEGLER-NATTA CATALYSTS.

摘要

The invention relates to concentrated low-viscosity solutions of alkaline earth alkoxide compounds M(OCH2R6)2-a-b(OR7) a[O(CHR8)nOR9]b in a mixture of a metal alkyl compound M(R10R11) in aprotic solvents, where M is an alkaline-earth metal chosen from Mg, Ca, Ba, Sr; OCH2R6 is an alkoxide radical comprising at least 3 and at most 40 carbon atoms having a branch in position 2 in relation to the O function, thus R6 = -CHR12R13 with R12, R13 = mutually independent alkyl radicals C1-C18; R7 is an alkyl radical having 2-15 carbon atoms, which is either linear or has a branch in a position = 3 (in relation to the O function); R8 is an alkyl radical comprising 1 -6 carbon atoms, which is either linear or has a branch in a position = 3 (in relation to the O function); R9 has an alkyl radical with 2-15 carbon atoms, which is either linear or has a branch; R10 and R11 are any alkyl radicals comprising 1-15 carbon atoms, n = an integer from 1 to 4, a + b = 2, wherein a and b can assume values from 0 to 2 and the molar ratio of M(OCH2R6)2-a-b(OR7) a[O(CHR8)nOR9]b to M(R10R11) lies from 99.5:0.5 to 60:40.
