1. A method for preparing a modified thermoplastic resin, said method comprising:
(I) mixing
(A) a thermoplastic resin having a tg of 95° C. or greater and having a melt processing temperature of 250° C. or greater;(B) a silicone base comprising:
(i) 100 parts by weight of a diorganopolysiloxane gum having a plasticity of at least 30 and having an average of at least 2 alkenyl groups per molecule and(ii) 0 to 50 parts by weight of a reinforcing filler for every 100 parts of diorganopolysiloxane gum, wherein the weight ratio of said silicone base to said thermoplastic resin is from 0.5:99.5 to 85:15;(C) 0.01 to 5 parts by weight of a radical initiator for every 100 parts by weight of the silicone base, and(D) an adhesion additive, and (II) dynamically vulcanizing said silicone base at an elevated temperature, wherein the thermoplastic resin is selected from the group consisting of: Liquid Crystal Polymers, Polysulfone, Polyphenylsulfone, Polyethersulfone, Polyetherketone, Polyether-etherketone, Polyetherketoneketone, Polyethylenenaphthalate, Polyether-block-amide, Polyether-block-copolyamid, Polyether-block-copolymer, Polyester-block-ether, Polyester-block-copolymer, Polyphenylene ether, Polyphthalamide, Polyarylamid, Polyimide, Polyamideimide, Polyethernitrile, Polycyclohexylene-dimethylene terephthalate, clohexylenedimethylene terephthalate acid, and acrylonitrile styrene acrylate. |
