Title:
METHOD FOR PRODUCING ANIONIC POLYMER
Document Type and Number:
WIPO Patent Application WO/2016/035866
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing an anionic polymer in an industrially advantageous manner whereby, at the time of anionically polymerizing a monomer by using a solvent having a higher boiling point than the polymerization temperature at atmospheric pressure, temperature control can be achieved by quickly removing the heat of the polymerization reaction with a simple device. [Solution] Disclosed is a method for producing an anionic polymer, the method involving anionically polymerizing a conjugated diene, an aromatic vinyl compound, or a mixture thereof under a condition where the amount of an inert gas present in 1 kg of a solvent having a higher boiling point than the polymerization temperature at atmospheric pressure is 20 mmol or less.
