Abstract

The present invention relates to non-agriculture articles which keep their properties during the use and degrade later on, until total disintegration and disappearance of the plastic. The invention further relates to a method for controlling the weathering resistance and the degradation of non-agricultural articles. The desired effect is obtained with specific combinations of degradant metals salts and stabilizers. The non-agricultural article of the present invention comprises an organic polymer, an organic salt of Fe, Ce, Co, Mn, Cu orVd and one more sterically hindered amine compounds.
