FIELD: polymer materials.
SUBSTANCE: polyester-based resin is prepared via copolymerization of high-concentration hydroxycarboxylic acid with aromatic dicarboxylic acid and aliphatic diol. Resin contains (a1) 45-99 mol % units of hydroxycarboxylic acid having 5 or less carbon atoms, (a2) 0.5-27.5 mol % units of aromatic dicarboxylic acid having 4 or less carbon atoms, the total molar percentage of indicated units being at least 95 mol % and dependence of polyester-based resin (ρ, kg/m3) on molar percentage of hydroxycarboxylic acid (M, mol %) satisfying the following formula: ρ = 1349+0.85M. Resin can easily be regenerated and products therefrom manifest good mechanical properties.
EFFECT: enabled preparation of resin having desired density, high gas impermeability and resistance against hydrolysis.
