FIELD: chemistry.
SUBSTANCE: present invention relates to a diol composition suitable for polyester material. Described is a diol composition suitable for polyester material containing diol as main component and an auxiliary component selected from a group consisting of organic acids, amino acids, amines, ammonia and carbon dioxide, and characterised by electrical conductivity in range of 0.6-30 mS/m, where diol is ethylene glycol, 1,3-propanediol, 1,2-propanediol, 1,3-butanediol, 1,4-butanediol or 2,3-butanediol. Also described is a polyester, obtained from said diol composition. Described is a moulded article made by moulding said polyester.
EFFECT: obtaining a polyester characterised by improved mechanical properties and stability during moulding and excellent colour shade.
