FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing a polydiene polymer. The method involves: (a) obtaining a growing polydiene polymer using a coordination catalyst in an active polymerisation mixture containing less than 20 wt % solvent with respect to total weight of the mixture; and (b) adding a polyhydroxy compound into the active polymerisation mixture. The polyhydroxy compound is characterised by equivalent molecular weight, which is defined as molecular weight of the polyhydroxy compound divided by the number of hydroxy groups per molecule, which is less than 80 g/mol and boiling point higher than 180°C. The invention also discloses a method of producing a polymer via continuous polymerisation and a polymer.
EFFECT: invention enables to obtain a polydiene polymer with improved properties.
