Dual-cured thermosets from glycydil methacrylate obtained by epoxy-amine reaction and methacrylate homopolymerization

Dual-curing is a processing technology based in the combination of two polymerization processes and proper selection formulation. This methodology allows preparation intermediate materials with tailored characteristics, which can be viscous-liquids or rubbery solids according to their application. Once applied, second stage performed leading high crosslinked network. Usually, different monomers are involved, unreacted monomer still present material. experiments during step, but it drip exuded storage. In work, commercial monomer, glycidyl methacrylate has been selected, because presence same molecule an epoxide group, react amines first dual-curing, group that thermally photochemically homopolymerized complete curing process. Diglycidylether bisphenol A added obtain gelled The evolution both steps studied by DSC FTIR. stability material confirmed characteristics final have evaluated TGA DMTA.
