Structure-Property Correlation in PTT/PP Blends with Improved Mechanical Performance
Abstract: The present work investigates a series of poly (trimethylene terephthalate) (PTT)/polypropylene (PP) blends prepared with varying PP concentrations in order to improve the overall performance of PTT, particularly with respect to mechanical properties and processability. PTT is a promising engineering thermoplastic owing to its balanced stiffness, resilience, and chemical resistance; however, its relatively high cost and processing limitations often restrict its wider application. In this context, blending with PP offers …
