More Information
Summary:A method for preparing a modified thermoplastic resin by mixing a thermoplastic resin having a t g of 95°C or greater and having a melt processing temperature of 250°C or greater with a silicone base comprised of 100 parts by weight of a diorganopolysiloxane gum and having an average of at least 2 alkenyl groups per molecule in conjunction with 0 to 50 parts by weight of a reinforcing filler along with a radical initiator. The silicone base and this combination are dynamically vulcanized to cure the silicone base at an elevated temperature.
