Patent ID: 8105461

Claim:
A method for disassembling a bonded structure obtained by bonding a first base member and a second base member to each other via a bonding film mainly made of a compound having a branched polyorganosiloxane skeleton having a structural unit expressed by a following general formula (1) at a terminal portion, a structural unit expressed by a following general formula (2) at a linking portion, and a structural unit expressed by a following general formula (3) at a branched portion: wherein each R independently represents a non-substituted hydrocarbon group; each Z independently represents a hydroxyl group or a hydrolytic group; each X represents a siloxane residue; a represents 0 or an integer of 1 to 3; b represents 0 or an integer of 1 or 2; and c represents 0 or 1, the method comprising: heating the bonding film into a molten state at a temperature equal to or higher than a glass transition point of the compound having the branched polyorganosiloxane skeleton; and separating the first and the second base members from each other.
