FIBRILLATION OF THERMOTROPIC LIQUID CRYSTALLINE POLYMER AS DISPERSED PHASE IN THERMOPLASTIC MATRIX

Based on rheological and morphological examinations,the formation behavior and the fibrillation conditions of a thermotropic liquid crystalline polymer as a dispersed phase in a thermoplastic matrix have been studied using models by Taylor,Cox and Grace. The fibrillation development has been characterized by We-number.viscosity ratio and critical burst time. The resuits show satisfactory agreement between the theoretical calculations and the experimental determmations.
