摘要: A description is given of an extrusion process for the preparation a low-dust stabiliser, using subcooled melt as granulation liquid, well amorphous modifications different stabilisers, including 2,2'-methylenebis(4-[1,1,3,3-tetramethylbutyl]-6-benzotriazol-2-yl-phenol), and β-crystalline modification 2-(2-hydroxy-3,5-di-tert-butylphenyl)-5-chlorobenzotriazole thereof. The affords products which are easy to handle flowable, have advantages regards their preparation, processing use stabiliser.
