摘要：

Different types of polymeric materials have been trade more resistant to photodegradation by protecting their surface with a UV-cured coating containing a HALS radical scavenger and a phenyltriazine UV absorber. The tridimensional polymer network formed by photo polymerization of an aliphatic poly urethane-acrylate telechelic oligomer proved to be very resistant to accelerated weathering in the presence of these light stabilizers. The chemical modifications occurring upon QUV-ageing were monitored by infrared spectroscopy, a very sensitive technique well suited for quantitative analysis at an early, stage of the photodegradation.
