Process for producing diene rubber polymer, diene rubber polymer produced therefrom, and core-shell structured acrylonitrile-butadiene-styrene graft copolymer containing the same

摘要

The present invention relates to a method for preparing a diene-based rubber polymer having relatively low gel content and high swelling index while having high polymerization conversion rate, a diene-based rubber polymer prepared therefrom and an acrylonitrile-butadiene-styrene graft copolymer of core-shell structure comprising the same as a core. Accordingly, the method for preparing a diene-based rubber polymer and the acrylonitrile-butadiene-styrene graft copolymer of core-shell structure comprising the diene-based rubber polymer prepared therefrom can be easily applied to the industries requiring them, in particular, an impact reinforcing agent industry.
