    Abstract: The present invention relates to a silicone-acrylic impact modifier having multi-layer structure and a thermoplastic resin composition containing the same, more precisely a silicone-acrylic impact modifier which is composed of i) silicone rubber seed containing one or more vinyl copolymers; ii) acrylic rubber core covering the seed; and iii) a shell containing one or more vinyl copolymers covering the acrylic rubber core, and a thermoplastic resin composition containing the same. The thermoplastic resin having the silicone-acrylic impact modifier of the present invention has improved impact resistance and colorability.

    Abstract: Disclosed are ophthalmic devices formed by a process comprising: (a) providing a reactive composition containing: (i) a polymerization initiator that is capable, upon a first activation, of forming two or more free radical groups, at least one of which is further activatable by subsequent activation; (ii) one or more ethylenically unsaturated compounds; and (iii) a crosslinker; (b) subjecting the reactive composition to a first activation step such that the reactive composition polymerizes therein to form a crosslinked substrate network containing a covalently bound activatable free radical initiator; (c) deactivating at least a portion of the covalently bound activatable free radical initiator at one or more selective regions of the crosslinked substrate network such that the crosslinked substrate network contains retained covalently bound activatable free radical initiator outside of the one or more selective regions and optionally within the one or more selective regions; (d) contacting the crosslinked substrate network with a grafting composition containing one or more ethylenically unsaturated compounds, wherein the contacting is conducted under conditions such that the grafting composition penetrates into the crosslinked substrate network; and (e) activating the retained covalently bound activatable free radical initiator such that the grafting composition polymerizes with the crosslinked substrate network, thereby forming grafted polymeric networks, outside of the selective regions and optionally partially within the selective regions.
