Abstract: A reactive hardenable polymer mixture which comprises A) at least one epoxy compound and B) at least one polycarboxylic acid compound in the form of a component selected from the group consisting of a) at least one compound of formula and (I) (Ia) wherein R1 is a radical derived from at least one polymeric product containing hydroxy groups selected from the group consisting of a polymerisation and a condesation product and a combination thereof in the form of polyesters, polymers each having a hydroxy number between 20 and 300, phenol resins having a hydroxy number between 100 and 800 and combinations thereof, R2 is a radical of an at least tetrabasic cyclic carboxylic acid having at least one COOH-group in an o- or peri-position to the ester bond, R5 is a radical of an at least dibasic cyclic carboxylic acid having at least one COOH-group in o- or peri-position to the ester bond and R5 may also be as defined for R2; b) at least one tetrabasic cyclic carboxylic acid compound having 2 carboxylic groups in an o- or peri-position or at least one anhydride group or both together with at least one of the OH-group containing compounds from which the above defined group R1 is derived; c) at least one compound corresponding to formula (I) or (Ia) as defined under a) but with the proviso that the anhydride groups are replaced at least partially by a free acid or ester group or by both; d) at least one compound as defined under b) wherein the anhydride groups of the polycarboxylic acid compounds are replaced at least partially by a free acid or ester group or by both; and e) any combination of a) to d), a process for the preparation of hardened products in hardening said composition.
