FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing dried granules for solid-phase polymerisation, involving: A) contacting the molten polymerisation product in the melt phase with the water-containing liquid; B) cutting in melting zone of melted polymerisation product in phase of molten metal submerged into water-containing liquid onto granules, wherein cutting of molten polymerisation product in melt phase takes place at residence time of not more than 1 s; C) removal of granules and water at temperature of at least 190 °C; D) granules drying; and E) feeding the dried granules into the solid-phase polymerisation reaction zone.
EFFECT: technical result is reduction of capital and operating costs.
