FIELD: chemistry. ^ SUBSTANCE: composition contains at least one matrix polyester polymer and at least one filler. Said matrix polymer is obtained via polymerisation of a mixture containing a dicarboxylic acid and a diol. Characteristic viscosity of the matrix polymer at 30C in a mixed solvent ranges from 0.7 to 0.9. The filler is selected from organoclay which exfoliate in polyamide, containing polymerised meta-xylene diamine links, and organoclay in form of nanoplates. ^ EFFECT: obtaining compositions used to mould containers, demonstrating improved gas-permeability characteristics. ^ 38 cl, 1 tbl, 5 dwg, 12 ex |
