Abstract: 1. Polymeric material on the basis of renewable raw materials, containing a reaction product produced by cross-linking from 10-90% by mass of a triglyceride with at least 2 epoxy and/or aziridine groups and 5-90% by mass of a polycarboxylic acid anhydride, manufactured from cyclic polycarboxylic acids with at least 2 free carboxylic acid groups, with 0.01-20% by mass of a polycarboxylic acid as an initiator. 2. Polymeric material according to Claim 1, characterised in that the epoxidised triglycerides are selected from soya oil, linseed oil, perilla oil, tung oil, oiticica oil, safflower oil, poppy oil, hemp oil, cottonseed oil, sunflower oil, rape oil, triglycerides from euphorbia plants such for example as euphorbia-iagascae oil, and highly-oleic triglycerides such for example as highly-oleic sunflower oil or euphorbia iathyris oil, groundnut oil, olive oil, olive seed oil, almond oil, kapok oil, hazelnut oil, apricot seed oil, beechnut oil, lupin oil, maize oil, sesame oil, grapeseed oil, lallemantia oil, castor oil, oils of sea creatures such as herring oil and sardine oil or menhaden oil, whale oil and triglycerides with a high proportion of saturated fatty acids which are subsequently converted to an unsaturated condition by dehydration, or mixtures thereof. 3. Polymer material of Claim 2 or 3, characterized in that epoxydazed triglycerides further contain hydroxylated triglycerides, for example ricin oil. 4.

Polymeric material according to at least one of Claims 1 to 4, characterised in that a di- or tricarboxylic acid is used as a polycarboxylic acid. 6. Polymeric material according to Claim 5, characterised in that the polycarboxylic acid is selected from citric acid derivates, polymerised tall oils, azelaic acid, gallic acid, di- or polymerised oleoresin acids, di- or polymerised anacardic acid, also cashew nut shell liquid, polyuronic acids, polyalginic acids, mellitic acids, trimesic acids, aromatic di- and polycarboxylic acids such for example as phthalic acid, trimellitic acid, hemimellitic acid, pyromellitic acid and their aromatically substituted derivates such for example as hydroxy or alkyl phthalic acid, unsaturated cyclic di- and polycarboxylic acids such for example as norpinic acid, heterocyclic di- and polycarboxylic acids such for example as loiponic acid or cincholoiponic acid, bi-cyclic di- and polycarboxylic acids such for example as norbornene dicarboxylic acids, open-chained di- and polycarboxylic acids such for example as malonic acid and its longer-chained homologues and its substituted compounds such for example as hydroxy- and keto- di- and polycarboxylic acids, pectinic acids, humic acids, polymeric cashew nut shell liquid with at least two free carboxylic acid groups in the molecule, or mixtures thereof. 7. Polymeric material according to at least one of Claims 1 to 6, characterised in that it contains 2-98% by mass of a reaction product according to Claim 1 and 98-2% by mass of a filler. 8. Polymeric material according to at least one of Claims 1 to 7, characterised in that the filler is selected from the group of organic fillers on the basis of cellulose-containing materials such as wood flour, sawdust or timber waste, rice husks, straw and flax fibres on the basis of proteins, particularly sheep wool and inorganic fillers on the basis of silicates and carbonates such as sand, quartz, corundum, silicon carbide and glass fibres, or mixtures thereof. 9. Polymeric material according to at least one of Claims 1 to 8, characterised in that during production of the reaction product, 0.01-10% by mass of a catalyst are added. 10. Polymeric material according to Claim 9, characterised in that the catalyst is selected from tertiary amines such as N, N'benzyldimenthyl aniline, imidazol and its derivates, alcohols, hydroxycarboxylic acids such as lactic acid or salicylic acid, and thio acids and organophosphorus compounds, particularly triphenylphosphite, trisnonylphenylphosphite, and bis-.beta.-chloroethylphosphite, bi-cyclic amines such as [2.2.2.] diazabicyclooctane, chinuclidine or diazabicycloundecenes, or mixtures thereof. 11. Polymeric material according to at least one of Claims 1 to 10, characterised in that it contains in addition a flame-retardant selected from the group aluminium hydroxide, halogen, antimony, bismuth, boron or phosphorus compounds, silicate compounds or mixtures thereof.
