    Article
    Restricted access - publisher's policy
    In this work, the kinetics of curing of a new family of interpenetrating polymer networks (IPNs) obtained by co-formulation of a photocurable acrylic resin with a thermocurable epoxy/anhydride mixture is studied. The first ...
  • Shape-memory actuators based on dual-curing thiol-acrylate-epoxy thermosets 

    Russo, Claudio; Fernández Francos, Xavier; Flor López, Sílvia de la (2020-01-01)
    Article
    Open Access
    In this work, new shape-memory thermosets have been developed using a thiol-acrylate-epoxy dual-curing system. A previously studied system has been successfully modified, introducing different amounts of tri(2,3-epoxypro ...
