The present disclosure relates to a method of preparing a large particle sized rubbery polymer and a rubber-reinforced thermoplastic resin using the same, and more particularly, to a method of preparing large particle sized rubbery polymer characterized by including: a first polymerization step for adding 0 to 80 wt% of a monomer in bulk with respect to a total monomer added to prepare a rubbery polymer to a reactor to perform a reaction for 0 to 8 hours; and a second polymerization step for continuously inputting 20 to 100 wt% of a monomer remaining after the first polymerization step to a lower portion of the reactor for 3 to 15 hours after the first polymerization step to perform a reaction, and to a rubber-reinforced thermoplastic resin using the same. The present disclosure has effects of preparing a large particle sized rubbery polymer with excellent diffusion efficiency into a particle of a monomer and a shorten polymerization time and further enhancing tensile strength, flowability, and whiteness of a rubber-reinforced thermoplastic resin using the same. |
