, (2008/06/13)
The present invention relates to the preparation of bis(siloxane) derivatives of the chemical formula(I) which are useful for as an initiator to group transfer polymerization. The initiators of the formula(I) can be obtained from reacting lithium diisoalkylamide of the formula (III) and diester compounds of the formula(IV) with trialkylchlorosilicon of the formula(V) STR1 Wherein, R and R' stand for a straight or branched chain of aliphatic hydrocarbons, n is integer of 0-2. STR2 Wherein R is the same as the R in formula(I) STR3 Wherein R and n are the same as the R and n in the formula(I) Wherein R stands for methyl or ethyl group.
