Abstract
The present invention relates to a composition for preparing a SAN copolymer, a SAN copolymer, a preparation method therefor, a heat-resistant ABS resin blend comprising the same, and heat-resistant ABS pellets. Specifically, the present invention provides a composition for preparing a SAN copolymer, the composition comprising a monomer mixture, and ethylene glycol dimethacrylate as a chain extender, wherein the monomer mixture comprises 60 to 75 wt % of an α-methylstyrene monomer and 25 to 40 wt % of an acrylonitrile-based monomer based on the total weight of the monomer mixture; and the ethylene glycol dimethacrylate is contained in an amount of 0.001 to 0.15 parts by weight based on 100 parts by weight of the monomer mixture.
