摘要： The present invention addresses the problem of providing an organic-inorganic hybrid prepolymer, whereby synthesis can be facilitated and the hardening temperature thereof can be reduced, an organic-inorganic hybrid material obtained from said prepolymer, and an element sealing structure formed using said material. The organic-inorganic hybrid prepolymer is prepared by a condensation reaction of (A): a polydimethylsiloxane having a silanol group at a terminal end thereof, the weight-average molecular weight (Mw) thereof being 3,000-100,000, and the molecular weight distribution coefficient (Mw/Mn, where Mn is the number-average molecular weight) being 1.3 or lower; and a compound (B) which is at least one species selected from the group consisting of (B-1); a metal and/or metalloid alkoxide and/or an oligomer of the abovementioned alkoxide, (B-2); a complete or partial hydrolysate of the alkoxy group of (B-1), and (B-3); a condensation reaction product of (B-2) or (B-2) and (B-1).

摘要： Disclosed herein are a phenyl-modified hybrid prepolymer, a phenyl-modified polydimethylsiloxane-based hybrid prepolymer, and a phenyl-modified polydimethylsiloxane-based hybrid polymer capable of controlling material hardness or surface tackiness depending on the intended use or purpose. A phenyl-modified hybrid prepolymer (B) is prepared by subjecting polydimethylsiloxane having trialkoxysilyl groups at both ends, phenyltrialkoxysilane, and diphenyldialkoxysilane to hydrolysis and condensation reaction. A phenyl-modified polydimethylsiloxane-based hybrid prepolymer (C) comprises (B), and is preferably prepared by mixing (B) and a phenyl-modified hybrid prepolymer (A) prepared by condensation reaction between polydimethylsiloxane having silanol groups at both ends and phenyltrialkoxysilane. The phenyl-modified polydimethylsiloxane-based hybrid polymer is obtained by heating and solidifying (C).
