Synthesis and Cationic Crosslinking of Polymethacrylate Having Spiro Orthoester Group in the Side Chain, and Decrosslinking of the Obtained Network Polymer

Abstract

Polymethacrylates having a spiro orthoester group in the side chain were synthesized by the radical polymerization of the corresponding methacrylate and copolymerization with methyl methacrylate. The obtained polymers underwent crosslinking in the presence of a cationic initiator in chlorobenzene at 0°C for 1h to afford the network polymers, which underwent decrosslinking in the presence of a cationic initiator in chlorobenzene at 20°C for 24h to recover the solvent-soluble original polymers.
