Abstract
The present invention relates to a method of preparing a graft polymer, which includes: preparing a second diene-based rubber polymer by enlarging a first diene-based rubber polymer with an acidic group-containing acrylic polymer; preparing a first mixture comprising the second diene-based rubber polymer and a non-ionic emulsifier; and preparing a graft polymer latex by polymerizing an aromatic vinyl-based monomer and a vinyl cyanide-based monomer in the presence of the first mixture.
