摘要 |
The invention relates to the use of fine-particle polymer powders, containing at least one UV absorber for the stabilisation of polymers, in particular, polyolefins, against the effects of UV radiation. The invention further relates to stabiliser mixtures for the stabilisation of polymers against the effects of UV radiation, oxygen and heat, comprising, amongst others, said polymer powders and a method for the stabilisation of polymers, in particular, polyolefins against the effects of UV radiation, oxygen and heat, characterised in that effective amounts of said stabiliser mixtures are added to the polymers, in particular, the polyolefins. Furthermore, the invention relates to polymers stabilised against the effects of UV radiation, oxygen and heat, in particular, polyolefins, which comprise an effective amount of said polymer powders or stabiliser mixtures and objects produced from said stabilised polymers in particular, polyolefins. |
