Adhesive composition containing resin having carbon-carbon multiple bond

An adhesive composition comprising:

• a polymer that contains a unit structure of Formula (1):
• L1-O-T1-O Formula (1)
• where L1 is a divalent group of Formula (3) or a divalent group of Formula (4):
• where R1, R2, and R3 are independently a C1-10 alkyl group, a C1-4 fluoroalkyl group, a hydroxy group, an allyl group, an allyloxy group, an amino group, a cyano group, a nitro group, an acyl group, an acyloxy group, a carboxy group, a group containing a tertiary-carbon structure, a cyclic alkyl group, or a combination of these, L2 is a sulfonyl group, a carbonyl group, an ester group, an amido group, a sulfinyl group, or a sulfonamido group, and each of n1, n2, and n3 is an integer of 0 to 4, and
• T1 is a fluoroalkylene group, a cyclic alkylene group, an arylene group having a substituent, or a combination of an arylene group optionally having a substituent and a fluoroalkylene group or a cyclic alkylene group, and that contains, at a terminal or in a side chain or the main chain, at least one group containing a structure of Formula (2-A):
• —C≡C— Formula (2-A)
• wherein when Formula (2-A) exists at a terminal or in a side chain of the polymer, it is the following monovalent group:
• —C≡CH and when Formula (2-A) exists in the main chain of the polymer, it is a divalent group.
