The invention relates to a process to prepare a condensation polymer containing ester groups and at least one amide group in the backbone, having at least one beta -alkyl-substituted beta -hydroxyalkylamide end group and having a hydroxy alkylamide functionality between 2 and 250. A polyvalent carboxylic acid reacts with an alkanolamine to form a hydroxy-alkylamide from which a polyesteramide is obtained through polycondensation. The obtained polymer may, for example, be used in a thermosetting powder paint composition or in a toner composition.
