Abstract: The invention relates to a method to prepare a precursor for a polymer or to prepare a polymer, the polymer comprising at least one unit of formula (I) or at least one unit of formula (II) having a tertiary amine and a pendant carboxyl group Furthermore the invention relates to a precursor or polymer comprising at least one unit of formula (I) and/or at least one unit of formula (II) and to the use of such precursor or such polymer in extrusion, injection moulding, compression moulding, transfer moulding, foam moulding, thermoforming, rotation moulding or 3D printing.

Abstract: The invention relates to a method to prepare a composition comprising an epoxy-based covalent adaptable network. The method comprises the steps of a) contacting a compound A and a compound B in controlled amounts to obtain a mixture comprising a curing agent. The compound A has a? functional groups of the type —C(?O)ORx and/or of the type —C(?O)— with the a? functional groups being arranged in pairs, positioned at a controlled distance from each other. The compound B has b? primary amine functional groups with the b? primary amine functional groups being arranged in pairs, positioned at a controlled distances from each other. b) contacting the mixture obtained in step a) with at least one compound C having epoxide functional groups to obtain the epoxy-derived covalent adaptable network. The invention further relates to compositions obtainable by such method.
