Abstract
Disclosed is a silicone impact modifier with a high refractive index. The silicone impact modifier can include (A) a rubber core including (a1) an organosiloxane cross-linked (co)polymer with a particle size of about 50 to about 400 nm and (a2) an alkylacrylate-styrenic aromatic compound cross-linked copolymer; and (B) a plastic shell including a vinyl (co)polymer. The refractive index of the silicone impact modifier of the present invention can be about 1.49 to about 1.59.
