ABSTRACT:
Diethers of general formula: ##STR1## where R, R.sup.I, R.sup.II, R.sup.III, R.sup.IV and R.sup.V are the same or different and are H, C.sub.1-18 linear or branched alkyl, C.sub.5-18 cycloalkyl, C.sub.6.about. aryl, C.sub.7-18 alkylaryl or C.sub.7-18 arylalkyl radicals, provided that when R is alkyl, R.sup.I is other than H or alkyl and when R.sup.I is alkyl, R is other than H or alkyl; R.sup.VI and R.sup.VIII are the same or different and are C.sub.1-18 linear or branched alkyl, C.sub.5-18 cycloalkyl, C.sub.6-18 aryl, or C.sub.7-18 arylalkyl radicals; and two or more of R to R.sup.V may be bonded to form a cyclic structure having 5 to 18 carbon atoms.
The diethers are particularly useful in the preparation of Ziegler-Natta catalysts.
