Abstract
[Problem to be Solved] Provided is a method for producing a non-petrochemical-derived conjugated diene polymer using an alcohol derived from a non-petrochemical raw material. [Means to Solve the Problem] In the present invention, the method is characterized in that a non-petrochemical-derived conjugated diene polymer is produced using an alcohol derived from a non-petrochemical raw material having an iron content of 0.0001 mg/L to 2 mg/L.
Claims10
A method for producing a non-petrochemical-derived conjugated diene polymer using an alcohol derived from a non-petrochemical raw material, comprising the steps of:
- using an alcohol having an iron content of 0.0001 mg/L to 2 mg/L derived from a non-petrochemical raw material, bringing the alcohol into contact with a catalyst and carrying out heating to produce a conjugated diene having C4 to C12 carbons;
- and
- polymerizing a monomer containing the conjugated diene to produce a non-petrochemical derived conjugated diene polymer.
