METHOD FOR EXFOLIATING ORGANOCLAY TO PRODUCE A NANOCOMPOSITE

Nano-composites that comprise a thermoplastic polymer (TPO) and an exfoliated organoclay are prepared by a method comprising contacting under exfoliating conditions at least one molten TPO polymer with at least one organoclay and at least one exfoliating agent of H-TEMPO or an amine precursor to H-T...

Beschreibung
Zusammenfassung:	Nano-composites that comprise a thermoplastic polymer (TPO) and an exfoliated organoclay are prepared by a method comprising contacting under exfoliating conditions at least one molten TPO polymer with at least one organoclay and at least one exfoliating agent of H-TEMPO or an amine precursor to H-TEMPO such that the exfoliating agent exfoliates the organ-oclay. L'invention porte sur un procédé de fabrication de nanocomposites qui comprennent un polymère thermoplastique (TPO) et une argile organique exfoliée, comprenant la mise en contact dans des conditions d'exfoliation d'au moins un polymère TPO fondu avec au moins une argile organique et au moins un agent d'exfoliation de H-TEMPO ou d'un précurseur amine pour H-TEMPO, de façon à ce que l'agent d'exfoliation exfolie l'argile organique.
