A novel tandem photochemical route to PMMA copolymer degradation sequential HAT and XAT reactions involving silanes
We report a tandem HAT/XAT mechanism for the scission of poly(methyl methacrylate)-co-poly(methyl α-chloroacrylate) copolymers. Silyl radicals, generated from silanes via HAT, facilitate halogen abstraction from the polymer main chain and subsequent chain degradation. The kinetics and versatility were investigated using different photoinitiators, providing an efficient radical-mediated strategy for upcycling non-hydrolyzable polymers.
