FIELD: chemistry.SUBSTANCE: present invention relates to use of carbonyl compounds to reduce content of emissions from a polymer in the space over a product in accordance with VDA 277 requirements, preferably for reducing emissions of 2-methyl-propene in the space over a product in accordance with VDA 277 requirements. The carbonyl compounds are selected from a group comprising an aromatic carboxylic acid with value of pKa measured in dimethylsulphoxide (DMSO) of at least 10.5, a fatty acid amide and a fatty acid ester.EFFECT: use of said carbonyl compounds in the polymer composition reduces weight content of emissions in the space over a product, particularly emission of 2-methyl-1-propane according to VDA 277 by at least 30%.17 cl, 1 tbl |
