The environmental and accelerated photodegradation of two polypropylene (PP) films (high and low crystallinity) were investigated. FT-IR measurements coupled with derivatization reactions (NO and SF 4 ), elongation at break tests and gel permeation chromatography technique were used to monitor the d
Changes in the ultimate properties brought about by outdoor weathering during the rainy season of polypropylene (PP) films were studied. The results obtained showed that the draw ratio l d , tensile stress s b , breaking ratio l b , breaking factor (BF), work draw U d , and work for rupture U r all
The yield properties of about 500 h of outdoor weathering (in the rainy season ) of polypropylene (PP) films have been studied. The yield strain, plastic strain, and initial modulus, work of yield attained local maxima at 48-and 240-h exposure time; elastic strain attained near double maxima at thes
