The photooxidation stability of PVC foils with various thicknesses (0,4; 0,2; 0,3 and 0,14 m m ) intended f o r agricultural use is investigated during accelerated and natural ageing. The surface state variations are investigated by surface crazing, total c o l o u r variation and chemical composition of t h e surface layer (IR-spectra of MIR-IR-spectroscopy). The foil volume variations are investigated by m e a n s of differential IR-spectra, light transmission decrease and t h e specific elongation. An analogy in t h e PVC f o i l s properties o f 0,4 mm thickness both f o r accelerated and natural ageing is observed. It is established t h a t during t h e 12 months induction period of t i m e f o i l s change negligibly t h e i r properties. The original properties of foils with thickness of 0,14 mm weathering f o r 15 months have changed less.
