Abstract: The present invention concerns a two-part curable composition comprising: ?a first part (component A) comprising: —at least 51% by weight based on the total weight of the first part, of one or more cyanoacrylate monomer(s); —a transition metal complex; and —an antioxidant; ?a second part (component B) comprising: —a per-compound; —at least one Michael acceptor M selected from the group consisting of (meth)acrylic monomers, (meth)acrylic functionalized oligomers, (meth)acrylic functionalized resins, and mixtures thereof; provided that the composition comprises (in the first part and/or in the second part) at least one compound C comprising a radical -EWG1-CH2-EWG2- wherein EWG2 and EWG1 are independently of each other an electron withdrawing group.

Abstract: The present invention refers to a curable two-part adhesive composition comprising a first part comprising one or more cyanoacrylate monomer(s), one or more (metha)acrylate monomer(s), a per-compound and, optionally, additives to control viscosity and rheology; and a second part comprising: a non-reactive diluent and a transition metal catalyst, and optionally an electron rich initiator for cyanoacrylates. It also relates to a syringe or a cartridge comprising said two-part curable composition, to the use of such composition for bonding substrates, to the use of such composition filling depressions, cracks or holes in a substrate or between substrates to a method for bonding substrates using said composition, and to a repair method for filling depressions, cracks or holes in a substrate or between substrates using said composition.

Abstract: The present invention concerns a two-part curable composition comprising: •a first part (component A) comprising: —at least 51% by weight based on the total weight of the first part, of one or more cyanoacrylate monomer(s); —a transition metal complex; and—an antioxidant; •a second part (component B) comprising: —a per-compound; —at least one Michael acceptor M selected from the group consisting of (meth)acrylic monomers, (meth)acrylic functionalized oligomers, (meth)acrylic functionalized resins, and mixtures thereof; provided that the composition comprises (in the first part and/or in the second part) at least one compound C comprising a radical -EWG1-CH2-EWG2- wherein EWG2 and EWG1 are independently of each other an electron withdrawing group.

Abstract: The present application is directed to a method for preparing a cyclic carbonate functional polyester, said method comprising the stages of (A) reacting glycerine carbonate with an anhydride to form an Adduct (A), (B) reacting said Adduct (A) with at least one polyepoxide compound to form an Adduct (B), and (C) reacting said Adduct (B) with at least one polycarboxylic acid to form said cyclic carbonate functional polyester.
