, R and R
1
-R
10
groups optionally contain one or more hetero-atoms replacing carbon atom, hydrogen atom or the both, said heteroatom is selected from the group consisting of nitrogen, oxygen, sulfur, silicon, phosphorus and halogen atom, and A represents carbon atom or silicon atom. The present invention also relates to a method for the preparation of the silicon ether compounds of general formula (I) and a process for polymerization of olefins.
