The structure of annealed polypropylene (PP) fibers is studied interferometrically using two-beam Pluta polarizing interference microscope connected to a device to study the draw ratio with birefringence changes dynamically. Relations of drawing changes with some optical and physical parameters are
## Abstract Dry and wet annealing of isotactic polypropylene fibers was carried out under constant length at 120Β°C in air and in glycerine environments with annealing times ranging from 1 to 30 h. A detailed analysis of the infrared spectrum of samples annealed, especially in air, showed clear evid
## Abstract This paper is devoted to the preparation of thermoplastic nanocomposites of polypropylene (PP) and different amounts of singleβwalled carbon nanotubes (SWNTs) in the range 0.25β2 wt %. The effect of SWNT content on the dynamic mechanical behavior, thermal degradation, crystalline struct
