United KingdomResearchers at Ehime University have developed a new molecular design strategy that enables carbon-carbon (C-C) backbone polymers—typically resistant to degradation—to break down under basic conditions without compromising their performance. By integrating alkoxycarbonylmethylene (ACM) units into polymer structures, the team demonstrated that these polymers can undergo controlled degradation via a retro-Michael reaction mechanism. This method was tested on various polymers like polystyrene and PMMA, where the addition of ACM units allowed for significant molecular weight reduction under mild conditions, unlike traditional versions of these materials. Importantly, the inclusion of ACM units did not negatively impact the thermophysical properties of the polymers; in some cases, it even enhanced them. The study suggests a promising pathway for creating more sustainable plastics that balance durability with environmental manageability.
