Title:
METHOD OF PREPARING CONJUGATED DIENE-BASED POLYMER AND METHOD OF PREPARING GRAFT COPOLYMER COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/060147
Kind Code:
A1
Abstract:
The present invention relates to a method of preparing a conjugated diene-based polymer, the method comprising the step of initiating and conducting polymerization while continuously introducing conjugated diene-based monomers into a reactor, thereby producing a conjugated diene-based polymer, wherein an emulsifier is added before the initiation of polymerization, and also at a time when the degree of polymerization conversion is 31% to 80%. More specifically, the present invention relates to a method of preparing a conjugated diene-based polymer, capable of reducing the total amount of an emulsifier, and to a method of preparing a graft copolymer comprising same.
