ADHESIVE COMPOSITION, FILM ADHESIVE, AND PROCESS FOR PRODUCTION OF THE COMPOSITION

摘要

An adhesive composition containing as the main component a polymer obtained by subjecting a monomer composition comprising styrene, a (meth)acrylic ester having a cyclic structure, and an alkyl (meth)acrylate having a chain structure to copolymerization. The polymer contains a styrene block segment and is therefore improved in heat resistance, bond strength under high-temperature conditions, alkali resistance, and easiness of peeling after high-temperature process. Thus, the invention provides an adhesive composition which exhibits high heat resistance, high bond strength under high-temperature conditions, and high alkali resistance and which is easy to peel after high-temperature process.
