Abstract
(EN)
The present invention relates to diene-based rubber latex having an ultra large diameter containing a polymer aggregate, a method for manufacturing same, and a graft copolymer having a core-shell structure having excellent impact strength and surface properties comprising same. The present invention provides diene-based rubber latex in which based on 100% by weight of the total rubber particles, 14% to 26% by weight exhibits a particle diameter of 100 nm or more and less than 300 nm, 62% to 81% by weight exhibits a particle size of 300 nm or more and less than 800 nm, and 5% to 14% by weight exhibits a particle size of 800 nm or more and less than 1000 nm.
