[ That which is claimed is:] [1.] A method for preparing a thermoplastic elastomer, said method comprising:(I) first mixing(A) a thermoplastic resin selected from the group consisting of a polyolefin and a poly(butylene terephthalate),(B) a diorganopolysiloxane having a plasticity of at least 30 and having an average of at least 2 alkenyl radicals in its molecule,(C) an organohydrido silicon compound which contains an average of at least 2 silicon-bonded hydrogen groups in its molecule,(D) optionally, a reinforcing filler and(E) a hydrosilation catalyst, ponents (C) and (E) being present in an amount sufficient to cure said diorganopolysiloxane (B); and(II) dynamically curing said diorganopolysiloxane (B), rein the amount of said diorganopolysiloxane (B) used is such that at least one property of the thermoplastic elastomer selected from tensile strength or elongation is at least 25% greater than the respective property for a corresponding blend wherein said diorganopolysiloxane is not cured and said thermoplastic elastomer has an elongation of at least 25%.
