ADHESIVE COMPOSITION COMPRISING AROMATIC POLYETHER DERIVATIVE

WIPO Patent Application WO/2012/020665

A1

[Problem] To provide a highly thermostable adhesive composition which dissolves easily into various organic solvents and which is capable of forming an adhesive layer with sufficient thickness and excellent coating properties, wherein the adhesive layer has an extremely small thermogravimetry loss in thermal processes such as metal bump bonding, CVD, ion diffusion processes, etc. and has excellent adhesion. [Solution] An adhesive composition comprising a polymer having a unit structure represented by general formula (1). (In the formula: X represents a sulphonyl group or a carbonyl group; Ar1 and Ar2 each represents a C6-30 arylene group; and T1 represents a combination of a fluoroalkylene group, a cyclic alkylene group, a substituted arylene group or an optionally substituted arylene group and a fluoroalkylene group or a cyclic alkylene group.) The arylene group is a phenylene group, a naphthylene group or an anthrylene group. The polymer is either a homopolymer having one type of unit structure, or a copolymer having at least two types of unit structures.
