Patent ID: 7399812

Claim:
A silicon ether compound having a general formula (I): wherein, R 1 -R 4 groups, which are identical to or different from each other, represent C 1 -C 20 linear or branched, aliphatic, alicyclic or aromatic hydrocarbyl, R 5 -R 8 groups, which are identical to or different from each other, represent hydrogen, halogen, or C 1 -C 20 linear or branched, aliphatic, alicyclic or aromatic hydrocarbyl, R 9 and R 10 groups, which are identical to or different from each other represent halogen, or C 1 -C 20 linear or branched, aliphatic, alicyclic or aromatic hydrocarbyl, and R 1 -R 10 groups optionally contain one or more hetero-atoms selected from the group consisting of nitrogen, oxygen, sulfur, silicon, phosphorus and halogen atom for replacing carbon atom(s), hydrogen atom(s) or the both, with the priviso that when all R 1 -R 3 groups are methyl, R 4 is not 2-(3-methyl-2-buten-1-yl)-cyclopropan-1-yl; when R 1 R 2 R 3 Si group represents tert-butyldimethylsilyl or tert-butyldiphenylsilyl, R 4 is not benzyl; and when both R 9 and R 10 are methyl, all R 5 -R 8 groups are hydrogen, and R 4 is C 1 -C 3 linear or branched alkyl, then R 1 -R 3 groups are not simultaneously ethyl.
