Melting, Crystallization and Dynamic Mechanical Properties of PTT/POE-g-MAH Blends

Abstract:

A series of poly(trimethylene terephthalate)/maleinized poly(octene-ethylene) copolymer blends are prepared and their melting, crystallization and dynamic mechanical propwerties were studied by using differential scanning calorimetry (DSC) and dynamic mechanical analyzer (DMA) respectively. The results suggest that the glass transition temperature of the blends shift to higher temperature because of the interaction between PTT and POE components. POE-MAH serves as a nucleating agent for the crystallization of PTT, and it increases the crystallizaiton rate of the blend and the start crystallizaiton temperature, but reduces the degree of crystallinity. Proper content of POE, e.g.1-2%, can improve the elastic modulus of the blend, but too much POE will depress the modulus.
