The present invention relates to a polymer having at least one pair of silicon atoms linked by a crosslinking by a straight chain or branched, or cyclic aliphatic hydrocarbon group, a heterocyclic ring containing group, or an aromatic ring containing hydrocarbon group which may include a cyclic structure, Based polymer compound obtained by subjecting a condensation product precursor containing a silane compound having a hydroxyl group and / or a hydrolyzable group to hydrolysis / condensation of a single substance or a mixture thereof, and the silicon-based polymer compound Resistant adhesive composition containing a silicon-based polymer compound having a silicon atom-containing ratio of 90 mol% or more as a thermosetting binder, wherein the ratio of silicon atoms having a direct bond to an aliphatic hydrocarbon group, a heterocyclic group-containing group or an aromatic ring-containing hydrocarbon group is at least 90 mol%. According to the high temperature resistant adhesive composition of the present invention, it can be used as an adhesive layer in a precise structure, and even when the bonded material is treated at a high temperature, the mass reduction is extremely low, and strong adhesion to thermal stress can be maintained. |
