A multi-reactive silicon compound has at least one polyalkyleneglycol substituent with the number average molecular weight being 200 to 10,000 as synthesized by reacting an organohalosilane compound having H—Si bonds with a polyalkyleneglycol ether compound having unsaturated substituents in the presence of a hydrosilylation catalyst. The multi-reactive silicon compound having polyalkyleneglycol substituents is very soluble in organic solvents and reactive to living polymeric ions with high thermal stability due to multiple functional groups, and active living groups. Thus, the addition of the multi-reactive silicon compound to a living polymer solution during an anionic or cationic polymerization reaction activates an intense substitution reaction under mild conditions to introduce a third functional group to the end or side chain of the polymer comprising a repeating monomer unit and provide organic-inorganic hybrid polymers.
A compound containing at least two functional groups with at least one polyalkyleneglycol substituent and at least two halogen substituents, the compound having a number average molecular weight of 200 to 10,000 and being represented by the formula (X)a(R)b(R1)cSi—C(R4)(R5)—Si(X)d(R)e(R2)f, in which:
A method for preparing a compound represented by the formula 1, (X)a(R)b(R1)cSi—C(R4)(R5)—Si(X)d(R)e(R2)f, in which:
