Polypropylene / poly (vinyl acetate) (PP / PVAc) (30 / 70) blend possesses higher thermal stability than PVAc and is stable below 300-degrees-C. The viscosity of the blend is lower than that of PP and PVAc at 220-degrees-C. The blend fibers have sheath-core morphology; the core is composed of PP fibrils because PP has reasonably higher viscosity than PVAc. Due to the reinforcement of PP fibrils, the tensile strength and modulus of the blend fibers were increased. The blend fibers drawn at 50-degrees-C possess better mechanical properties than those drawn at 90-degrees-C.
