Abstract
The present invention relates to a thermoplastic resin. More particularly, the present invention relates to a thermoplastic resin that is a graft copolymer having a seed-shell structure and includes a bimodal seed including a large-diameter rubbery polymer having an average particle diameter of greater than 2,000 Å and 3,500 Å or less and a small-diameter rubbery polymer having an average particle diameter of 500 Å to 2,000 Å; and an aromatic vinyl-vinyl cyan shell, wherein the aromatic vinyl cyan compound is included in an amount of 5% by weight to 28% by weight based on a total weight of the aromatic vinyl-vinyl cyan shell. In accordance with the present invention, a thermoplastic resin having a composition capable of improving graft density, and a thermoplastic resin composition capable of increasing dispersion and having high gloss due to inclusion of the thermoplastic resin are provided.
