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

Dependent claims

A method to prepare a polymer or to prepare a precursor for a polymer, said method comprising the steps of

a) providing at least one compound Y comprising a first functional group and a second functional group,
said first functional group comprising an anhydride group, a pair of carboxyl groups or a pair of derivatives of a carboxyl group, said anhydride group, said pair of carboxyl groups or said pair of derivatives of a carboxylic group of said first functional group comprising a first carbonyl group, a second carbonyl group, a first carbon atom positioned next to said first carbonyl group, a second carbon atom positioned next to said second carbonyl group and optionally a third carbon atom positioned between said first carbon atom and said second carbon atom, said first carbon atom, said second carbon atom and said optional third carbon atom being independently from each other substituted or non-substituted and,
said second functional group comprising a polymerisable group P1,
whereby in case a unsaturated bond is present between said first carbon atom and said second carbon atom, said unsaturated bond between said first carbon atom and said second carbon atom is not considered as polymerisable group P1 of said second functional group and whereby in case the bond between said first carbon atom and said second carbon atom is part of a cyclic or aromatic structure comprising an unsaturated bond in said cyclic or aromatic structure, said unsaturated bond present in said cyclic or aromatic structure is not considered as polymerisable group P1 of said second functional group;
b) providing an alcohol Z or a mixture of alcohols comprising alcohol Z or reacted with alcohol Z, said alcohol Z comprising at least one hydroxyl functional group and at least one polymerisable group P2, said alcohol Z further comprising a nitrogen atom, said nitrogen atom having three substituents comprising at least one carbon atom, said alcohol Z comprising a first carbon atom, a second carbon atom and optionally a third carbon atom between said nitrogen and said at least one hydroxyl functional groups of said alcohol Z, said first carbon atom, said second carbon atom and said optional third carbon atom being independently from each other substituted or non-substituted;
c) contacting said compound Y provided in step a) and said alcohol Z or said mixture of alcohols provided in step b).
