Organic-inorganic hybrid prepolymer and organic-inorganic hybrid material and device sealing structure

摘要

It is an object of the present invention to provide an organic-inorganic hybrid prepolymer capable of facilitating synthesis and lowering the curing temperature, an organic-inorganic hybrid material obtained from the prepolymer, and an element sealing structure using the material (A) a polydimethylsiloxane having a silanol group at the terminal, having a weight average molecular weight (Mw) of 3,000 to 100,000 and a molecular weight distribution index ( (B-1): metal and / or metalloid alkoxide and / or oligomer of the alkoxide, (B-2) :( B-1): (B-1) , (B-3): a condensation reaction product of (B-2) or (B-2) with (B-1), And at least one compound (B) are condensed with each other.
