FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing alkyde resins and can be used to produce polymer compounds, particularly high-quality bitumen. The method of producing alkyde resins involves reaction of a mixture of organic acids with a polyatomic alcohol at 160-180°C and molar ratio of mixture of organic acids to polyatomic alcohol equal to 1:1-2 until achieving acid number 5-50 mg KOH/g in the reaction mixture. The mixture of organic acids contains 80-87 wt % terephthalic acid, 8-15 wt % p-toluic acid, up to 0.4 wt % benzoic acid, up to 0.1 wt % carboxybenzaldehyde and water - the balance.
EFFECT: simple process of producing alkyde resins and low power consumption.
