Recently, polymer composites based on thermotropic liquid crystal polymer (TLCP) and conventional thermoplastics have attracted great attention because of their potential applications for high performance polymers and fibers. It is well known that thermal decomposition behavior of polymer composites is very important because it can affect the final properties for uses of polymer composites like the upper temperature limit of use. Although thermal properties of polymer composites composed of polyesters and TLCP have been widely investigated, little research for the kinetic analysis of thermal decomposition of TLCP/polyester composites have been performed so far. In this research, polymer composites based on poly(butylene terephthalate) (PBT) and TLCP were prepared by a process of melt blending, and thermal decomposition behavior of PBT/TLCP composites was investigated with thermogravimetric analysis at different heating rates. The kinetic parameters such as the activation energy, reaction order, and frequency factor of thermal decomposition reaction for PBT/TLCP composites were analyzed by using the single and multiple heating rate methods. |
