Thermo-Mechanical Characterization of a Thermoplastic Copolyetherester (TPC): Experimental Investigation

Thermo-Mechanical Characterization of a Thermoplastic Copolyetherester (TPC): Experimental... Abstract In this article, the thermo-mechanical characterization of poly(butylene terephthalate)/poly(tetramethylene oxide) (PBT/PTMO) is studied by thermal analysis, dynamic mechanical analysis, and uniaxial tensile tests. The results of poly(ether esters) show that the melting temperature is equal to T m =193 °C, which is 31 °C, lower than that of the melting temperature of poly(butylene terephthalate) (PBT). Its glass transition temperature, T g is equal to -61 °C, determined by DMA. The melting and cooling temperatures (T m , T c ) after aging at T0+48 h and T0+week are virtually unchanged. Moreover, the results of the tensile tests show that the effect of the low deformation rate reduces the friction resulting from the sliding mechanisms between the amorphous and crystalline parts. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Fibers and Polymers Springer Journals
