Impact modifier for a polymer composition and method for preparing the same |
摘要 |
Disclosed herein is an impact modifier for a polymer composition and a method of preparing the same. The impact modifier includes a core comprising a polyorganosiloxane, an acrylate polymer and a styrenic polymer; and a shell generally surrounding the core, the shell comprising a polymer attached to the core. The method includes providing a silicone rubber particle; adding a polymerizable styrenic compound into the silicone rubber particle; polymerizing the polymerizable styrenic compound within the particle to provide a styrenic polymer; adding a polymerizable acrylic compound into the silicone rubber particle; polymerizing the polymerizable acrylic compound within the silicone rubber particle to provide an acrylate polymer; and grafting a polymerizable compound onto the silicone rubber particle to provide a shell substantially surrounding the silicone rubber particle comprising the styrenic polymer and the acrylate polymer.
