Main-Chain Scission of Acrylic Polymers via Intrachain Transesterification and Their Application in UV-curable Dismountable Adhesives.

ABSTRACT: In this study, we report degradable acrylic polymers obtained by main-chain scission (MCS) via intramolecular transesterification and their application as UV-curable adhesives that allow for gentle dismounting. The solution polymerization of ethyl α-(hydroxymethyl)-acrylate (1) and cyclic allyl sulfide 2 afforded copolymers with ester bonds in their main chains, which underwent MCS in the presence of 1,5,7-triazabicyclo[4.4.0]-dec-5-ene (TBD). Similar bulk polymerization afforded cross-linked copolymers swollen in N,N-dimethylformamide (DMF), which were decomposed into soluble oligomers via MCS by TBD. Two glass plates were adhered by the bulk photopolymerization of 1 (90 mol %) and 2 (10 mol %) with strengths higher than 9.0 MPa. Soaking these pla
