ABSTRACT:
A method and composition for improving the impact resistance of thermoplastics is disclosed. An impact resistant thermoplastic is formed by forming a silicone containing thermosetting component, compounding it with a thermoplastic to form a silicone-thermoplastic mixture, disposing a catalyst on the mixture, and activating the catalyst while compounding the mixture with a thermoplastic. The silicone containing thermosetting component includes a first silicone compound containing hydride groups and a second silicone compound containing unsaturated groups. Activating the catalyst, preferably a platinum complex, causes the thermosetting component to cure, creating a silicone-thermoplastic semi-interpenetrating polymer network having higher impact resistance than the unmodified thermoplastic.
