FIELD: chemistry.

SUBSTANCE: description is given of the composition for making products from amine resin for processing smelts. The compositions are distinguished by that, they consist of the following components: A) from 95-99.9 mass % of molten polycondensates of melamine resins, free from solvents, with molar mass ranging from 300 to 300000. The polycondensates of melamine resins are mixtures of molten polytriazine ethers, with 4 to 1000 centres and have molar ratio of melamine or melamine derivative/C₁ - C₈ aldehyde 1:1.5 to 1:5; B) from 0.1 to 5 mass % weak acids as thermoinducible hardening agents, consisting of B1) acid conditioners of blocked sulfonic acid with general formula (I), R₁ = non-substituted or substituted aryl of diphenyl, R₂ = 4-nitrobenzyl, pentafluorobenzyl or substituting groups, where R₃ = non-substituted or substituted alkyl or aryl; R₄= H, C₁-C₁₂-alkyl, phenyl, C₂-C₉-alkanoyl or benzyl, R₅= H, C₁-C₁₂-alkyl or cyclohexyl, or R₃ and R₄ or R₅ together with atoms, to which they are bonded, form a 5-8-member ring, which can be closed by 1-2 benzo radicals, B2) C₄-C₁₈ aliphatic and/or C₇-C₁₈ aromatic carboxylic acids, B3) salts of alkaline metals or salts of ammonium phosphoric acid, B4) C₁-C₁₂-alkyl ethers or C₂-C₈-hydroxylalkyl ethers, C₇-C₁₄ aromatic carboxylic acids or inorganic acids, B5) melanin salts or guamines with C₁-C₁₈ aliphatic carboxylic acids, B6) anhydrides, monoesters or monoamides of C₄-C₂₀ carboxylic acids, B7) monoesters or monoamides of copolymers of unsaturated C₄-C₂₀ dicarboxylic anhydrates and ethylene unsaturated monomers of the C₂-C₂₀ olefins and/or C₈-C₂₀ vinyl aromatic type compounds, and/or B8) salts of C₁-C₁₂ -alkylamines and/or alkanoylamines with C₁-C₁₈ aliphatic compounds, C₇-C₁₄ aromatic or alkyl aromatic carboxylic acids, as well as inorganic acids of chloric acid, sulphur acid or phosphoric acid type, and C) if desired, up to 400 mass % of filler and/or consolidating fibres, up to 30 mass % of other reactive polymers of ethylene copolymers, copolymer of maleic anhydride, copolymer of modified maleic anhydride, poly(meth)acrylate, polyamide, type of polyester and/or polyurethane, and up to 4 mass % of stabilisers, based on polycondensates of melamine resin, UV absorbents and/or auxiliary substances. The method of making products from the above mentioned compositions is also described.

EFFECT: improvement of handling properties of the mould in molten state.
