Controlled photodegradation of phenyl vinyl ketone polymers by reinforcement with softer networks

Abstract

Polymer networks based on phenyl vinyl ketone were synthesized. The introduction of a second network enhanced the control over the material's photodegradation, as well as modulating the mechanical properties.

Main chain selective polymer degradation: controlled by the wavelength and assembly

“…Strategies to deconstruct vinyl polymers on demand with light thus traditionally rely on the translation of chain end or side chain functionalities into the main chains, such as the b-scission of polyvinyl ketones that enabled the design of light degradable polymers. [4][5][6][7] Sumerlin and coworkers have developed elegant avenues to photochemically decarboxylate polyacrylates to induce similar radical main chain scission. 8 Recent emerging avenues towards light controlled depolymerization guided by polymer chain ends are based on RDRP depolymerization.…”
