  • Nanocomposite comprising stabilization functionalized thermoplastic polyolefins
    Patent number: 7825182
    Abstract: This invention relates to nanocomposites comprising organo-clay and at least one stabilization functionalized thermoplastic polyolefin. Preferably the stabilization functionalized thermoplastic polyolefin is represented by the formula: T-(R1G)n wherein T represents the thermoplastic polyolefin Each R1 is a bridging group, preferably independently selected from the group consisting of C1 to C20 aliphatic; C1 to C20 aromatic; substituted C1 to C20 aliphatic; substituted C1 to C20 aromatic; C1 to C20 aliphatic ester; C1 to C20 aliphatic ether; C1 to C20 aliphatic amide; C1 to C20 aliphatic imide; n is the number of stabilization functional/bridging groups bound to T and may be from 1-300; and G is selected from one or more of phenols, ketones, hindered amines, substituted phenols, substituted ketones, substituted hindered amines, or combinations thereof.
    Type: Grant
