The effect of the natural weathering and o£ accelerated weathering on the changes in the tensile strength and relative elongation at break of the stabilized and non-stabilized demostic copolyesterether — Elitel-1 and of the commercial foreign-made copolyesterether — Arnitel EL 550, has been investigated. The relationship between the rate of ageing under natural weathering conditions and under accelerated weathering conditions in weatherometer has been established.
