Abstract
A new family of poly(keto ester)-poly(methacrylate) thermosets based on off-stoichiometric acetoacetate-acrylate/methacrylate formulations has been prepared and characterized. The first stage of curing is a self-limiting click Michael addition between acetoacetate and acrylate groups at room temperature and the second stage is a methacrylate radical photopolymerization. An analysis of the reaction kinetics confirmed that acetoacetate reacts selectively with acrylates, leaving methacrylates compl...
