Abstract
The present invention relates to a method for preparing large-sized diene-based rubber latex, and an acrylonitrile-butadiene-styrene graft copolymer comprising the same. More particularly, it relates to a method for preparing large-sized diene-based rubber latex having improved impact strength by controlling content and time of addition of a cross-linking agent and an emulsifier having critical micelle concentration (CMC) of 150 mg/L or less during preparation of the large-sized rubber latex, large-sized diene-based rubber latex prepared therefrom, and an acrylonitrile-butadiene-styrene graft copolymer and thermoplastic resin comprising the same.
