Title:
PROCESS FOR PRODUCING DIENE-BASED POLYMER
Document Type and Number:
WIPO Patent Application WO/2016/158084
Kind Code:
A1
Abstract:
The present invention is capable of attaining a high yield in production of a diene-based polymer. A diene-based-monomer solution is supplied as a starting material to a polymerization tank to produce a diene-based polymer. To the polymerization tank, a diene-based monomer or diene-based-monomer solution which has a lower temperature than the polymerization solution inside the polymerization tank is supplied separately from the supply of the starting material. In particular, in the case where a plurality of polymerization tanks are serially disposed, the lower-temperature diene-based monomer or diene-based-monomer solution is supplied to any of the polymerization tanks other than the first polymerization tank.
