Abstract
The present invention relates to a method for preparing a thermoplastic copolymer using monomer droplets, a thermoplastic copolymer prepared therefrom and a thermoplastic resin composition including the same. In the preparation method, monomer droplets including an aromatic vinyl-based monomer are injected after reaching a polymerization conversion ratio of 10% to participate in the reaction after initiating polymerization, and a thermoplastic copolymer having an increased average particle diameter may be prepared in high yield.
