<B> THERMOPLASTIC SILICON ELASTOMERS AND METHOD FOR PREPARING THE SAME <D> A method for preparing a thermoplastic elastomer is disclosed which comprises: (I) mixing (A) thermoplastic resin selected from the group consisting of a polyolefin and a poly (butylene) terephthalate), (B) a diorganopolisyloxane having a plasticity of at least 30 and having an average of at least 2 alkenyl radicals in its molecule, (C) a silicon organohydride compound that contains an average of at least 2 bonded hydrogen groups to silicon in its molecule, (D) optionally, a reinforcement charge and (E) a hydrosylation catalyst; and (II) dynamically cure the diorganopolisiloxane (B), in which the amount of the diorganopolisiloxane (B) used is such that at least one property of the thermoplastic elastomer selected for tensile strength or elongation is at least 25% greater than that respective property for a corresponding simple mixture in which the diorganopolisiloxane is not cured. |
