Effects of processing conditions on the phase morphology and mechanical properties of highly toughened polypropylene/polybutylene terephthalate (PP/PBT) blends

The effects of processing conditions were studied on the phase morphology and mechanical properties of the polypropylene/polybutylene terephthalate (PP/PBT) blends toughened by styrene-butadiene triblock copolymer thermoplastic elastomers. Highly toughened PP-based blends that exhibited increased impact strength (seven- to ninefold) and little loss of stiffness (< 15%) in comparison with neat PP resin were successfully developed through...
