STABILIZATION OF AGRICULTURE FILMS BY POLYMERIC HALS WITH PARTICULAR EMPHASIS ON POSSIBLE INTERACTIONS WITH AGROCHEMICALS

摘要

Polymeric HALS (Hindered Amine Light Stabilizers) are the UV-stabilizers of choice for LDPE based films. Despite the knowledge of general correlations forecast of the lifetime of films is difficult, due to UV-stabilizer-agrochemical interactions. Although, mechanism and level of interaction depend on the type of agrochemical, in particular polymeric HALS with secondary amine structure show strong interaction. This phenomenon seems to be product specific for this type of polymeric HALS.
