Original Abstract

Correlation of accelerated ageing data with outdoor exposure was carried out using non-UV-stabilized PP films – homopolymer, random copolymer (TOT C2 = 3.5 wt.%) and impact copolymer (TOT C2 =6.4 wt.%). Accelerated ageing was realized in Q-Sun Xe-1 exposure chamber using a filtered xenon light source and a dry cycle; outdoor exposure was carried out in Brno, representing the typical mid-European climate. The extent of photooxidative degradation was monitored using a carbonyl index, defined upon FITR absorption within 1700-1715 cm-1 wavenumber band. Accelerated ageing for all the materials investigated was carried out at temperatures 40, 50, 60 and 70 degC. Different times to degradation attained for individual temperatures were correlated with the weathering data after 6 months.
