    摘要: A cycloalkoxysilane, having utility as an electron donor in the Ziegler-Natta polymerization of olefinic monomers, of the structure (R'O)x(R')ySi(OR) 4-x-y wherein R is independently selected from the group consisting of alkyl radicals having 1 to 5 carbon atoms and acyl radicals having 2 to 5 carbon atoms, R' is independently selected from the group consisting of a cyclopentyl radical, a cyclohexyl radical a cycloheptyl radical and substituted radicals thereof, x is 1, 2, 3 or 4 and y is 0, 1 or 2.
