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

Abstract

The photodegradation of polymer materials represents a promising solution for addressing the challenges associated with plastic waste management within the environment. Vinyl ketone polymers, such as phenyl vinyl ketone (PVK), exhibit backbone degradation upon exposure to ultraviolet (UV) light. However, this property leads to significant degradation of PVK polymer materials within a few years under simulated sunlight conditions. While this is advantageous for waste management purposes, it can adversely impact the lifespan of these materials in practical applications. This study demonstrates a novel approach to control the degradation of PVK materials by incorporating a secondary network, based on poly(ethyl acrylate), within the polymer matrix. This approach allows for the manipulation of the material's mechanical properties while also enabling the controlled photodegradation of network materials.
