Abstract:
Provided are a rubber latex having a multi-layer structure, wherein an inner-layer rubber latex has a refractive index greater than that of an outer-layer rubber latex, a graft copolymer prepared from the rubber latex, a polyvinyl chloride (PVC) resin blend containing the graft copolymer, and a method of preparing the rubber latex. The PVC resin blend containing the graft copolymer including the rubber latex according to the present invention has improved color property and low-temperature impact strength than conventional PVC resins.
