  • Composition comprising at least two incompatible thermoplastic polymers and a compatibilizer, its method of preparation and its use
    Patent number: 7851553
    Abstract: The present invention relates to a composition comprising at least two incompatible thermoplastic polymers and at least one compatibilizer, to a method of preparing this composition, and to the use of said composition for the manufacture of thermoplastic articles or semi-finished products having, in particular, improved mechanical properties. A composition according to the invention is such that said polymeric compatibilizer includes at least two groups of polar and apolar units compatible with the respectively polymers, and it is characterized in that it comprises the product of a hot compounding reaction, in the presence of a crosslinking system, of said compatibilizer in the crosslinkable state with said thermoplastic polymers, in such a way that only said compatibilizer is crosslinked in said composition.

  • Cross-Linked Composition Comprising a Triblock Sequenced Copolymer, Method for the Production Thereof, and Uses of the Same
    Publication number: 20070208135
    Abstract: The invention relates to a cross-linked composition comprising at least one elastomer and at least one triblock block sequenced copolymer. The Invention also relates to a method for obtaining one such composition based on a system and a suitably selected crosslinking temperature. According to a preferred embodiment of the invention, the cross-linked composition can be transformed as a thermoplastic material. The inventive composition can be used in various applications, especially for producing conduits for the transfer of fluids, seals and insulation linings.
