Silicone Impact Modifier with High Refractive Index and Method for Preparing the Same

摘要

The silicone impact modifierwith high refractive indexaccording to the present invention comprises (A) a rubber core consisting of (a) an organosiloxane cross-linked (co)polymer with a particle size of 50~400 nm and (a) an alkylacrylate-styrene aromatic compound cross-linked copolymer; and (B) a plastic shell consisting of a vinyl (co)polymer. The refractive indexof the silicone impact modifier of the present invention is 1.49-1.59.
