Abstract: Tensile tests of polypropylene and its blends with polyethylene and other additives have been recorded by digital camcorder. Acoustic emission (AE) was monitored during tests by two transducers attached to test samples, allowing linear location of AE**ces. Tested materials exhibit large localized plastic deformation - necking - reaching hundreds of percent before failure. Image analysis procedure is designed for quantitative evaluation of axial and lateral strains and strain rates along the sample
