Abstract
A thermotropic liquid crystalline polymer (TLCP) based on hydroxybenzoic acid, hydroquinone and sebacic acid was used as a processing aid in the extrusion of high molecular mass polyethylene (HMMPE)/clay nanocomposites. Clay/TLCP with optimal mass ratio loading in HMMPE matrix has better thermal stability than that of clay or TLCP blends. Capillary rheometry experiments were carried out at processing temperature 190 °C with TLCP in the full nematic phase. TLCP is an effective processing aid agent with viscosity reduction in excess of 95%. The mechanism is proposed and analyzed by morphological study and surface analysis. TLCP has been shown to act as both a compatiblizer between nanoclay and the HMMPE matrix and a processing aid for the nanocomposite.
