POLYMER COMPOSITION COMPRISING STABILISERS AGAINST DEGRADATION BY HEAT, LIGHT AND/OR OXYGEN COMPRISING A STERICALLY HINDERED HYDROXYLAMINE (DERIVATIVE) AND A METAL OXIDE AND/OR CARBONATE AND/OR AN HYDROTALCITE

摘要

Compositions comprising a synthetic organic polymer and, as stabilizer, a combination of A) a sterically hindered hydroxylamine, or an ether or ester thereof, and B) a compound containing an oxo and/or hydroxyl group bonded to a metal atom, show an excellent stability against the deleterious effects of light, oxygen and/or heat. A combination of components A and B is also effective to stabilize a polyolefin or olefin copolymer film for agricultural applications against deleterious effects of light, oxygen, heat and pesticides.
