Zusammenfassung:	There is disclosed a method for preparing a thermoplastic elastomer composition which exhibits improved mechanical properties, said method comprising: (I) reacting, (A) a fluorocarbon resin with, (B) a grafting agent, in the presence of, (C) a radical initiator, to prepare a modified fluorocarbon resin; (II) mixing said modified fluorocarbon resin with (D) a silicone base consisting essentially of a diorganopolysiloxane gum having an average of at least 2 alkenyl radicals in its molecule and a reinforcing filler, (E) an organohydrido silicon compound which contains an average of a t least 2 silicon-bonded hydrogen groups in its molecule, and (F) a hydrosilation catalyst, components (E) and (F) being present in an amount sufficient to cure said diorganopolysiloxane; and dynamically curing said diorganopolysiloxane.
