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:in-line-formulae description="In-line Formulae" end="lead"?T-(R1G)nin-line-formulae description="In-line Formulae" end="tail"?WhereinT represents the thermoplastic polyolefinEach R1is a bridging group, preferably independently selected from the group consisting of C1to C20aliphatic; C1to C20aromatic; substituted C1to C20aliphatic; substituted C1to C20aromatic; C1to C20aliphatic ester; C1to C20aliphatic ether; C1to C20aliphatic amide; C1to C20aliphatic imide;n is the number of stabilization functional/bridging groups bound to T and may be from 1-300; andG is selected from one or more of phenols, ketones, hindered amines, substituted phenols, substituted ketones, substituted hindered amines, or combinations thereof.
