Rheological Properties and Spherulite Morphology of Poly(trimethylene terephthalate)/Rubber Blends

Abstract:

Poly(trimethylene terephthalate) (PTT), and three different rubbers(maleated styrene-butylene-co-ethylene-styrene copolymer (SEBS-g-MA), ethylene-propylene-diene copolymer grafted with maleic anhydride (EPDM-g-MA) and maleic anhydride grafted poly (ethylene-octene) (POE-g-MA)) were mixed in the melt state. Their rheological properties and spherulite morphology were investigated. Rheological properties shows torque decreases with the time increasing for all blends. PTT/SEBS-g-MA blend have better processability than PTT/EPDM-g-MA and PTT/ POE-g-MA blend. Polarizing optical microscopy (POM) experiments showed that the introduction of rubber chain greatly affects the size of the PTT spherulites. Small-sized PTT spherulites were formed when rubber added to PTT.
