In this study, we carried out the thermolysis of poly［p-（tert-butoxycarbonyloxy）styrene]（PBSt）prepared by radical polymerization and investigated the reaction mechanism for the formation of poly（p-hydroxystyrene）accompanying the elimination of isobutene and carbon dioxide from the tert-butoxycarbonyl（Boc）group in the side chain. We also discussed the reaction conditions for thequantitative transformation of the protected functional groups in the side chain of the polymer. Theadhesion of aluminum plates using a copolymer of p-（tert-butoxycarbonyloxy）styrene and glycidylmethacrylate（P（BSt-co-GMA））with a diamine cross-linker was carried out. The lap shear testrevealed that high adhesion strength was observed for the thermally cured specimen at 100℃ for 4 h,and that the strength drastically decreased after heating at 150℃ for 1 h, due to the decompositrionof the Boc group in the copolymer.
