Abstract
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 with a 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 with a 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.
