Abstract
Reactive blending of syndiotactic 1,2-polybutadine (SPB) and nylon 11 was carried out with a twin-screw extruder to obtain a thermoplastic vulcanizate (TPV) with good mechanical properties. A lamellar structure formed by continuous nylon 11 phase and long filamentous ligaments of SPB was observed for the TPV sample with a transmission electron microscope. Infrared spectra of nylon 11 films casted on SPB films show that chemical bonds between nylon 11 and SPB were formed after the curing of the films. Good mechanical properties of the TPV, which were owed to its morphology and strong adhesion at the interface, were investigated by peel tests and tensile tests.
