FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing a functionalised polymer. Described are versions of a method of producing a functionalised polymer comprising the following steps: (a) polymerisation of a conjugated diene monomer, optionally along with a monomer capable of copolymerisation with a conjugated diene monomer, in the presence of a coordination catalyst to form a polymer; (b) inhibiting said polymerisation step with a Lewis base; and (c) reaction of the polymer with a functionalising agent different from the Lewis base used at step (b). Described also is a functionalised polymer obtained using a method comprising the following steps: (a) polymerisation of a conjugated diene monomer, optionally along with a monomer capable of copolymerisation with a conjugated diene monomer, in the presence of a coordination catalyst to form a polymer; (b) inhibiting said polymerisation step with a Lewis base; and (c) reaction of the polymer with a functionalising agent different from the Lewis base used at step (b).
EFFECT: inhibiting polymerisation without destructive effect on the capacity of the reactive polymer to react with the functionalising agent, reduced risk of uncontrolled polymerisation, reduced contamination of equipment.
