63293-2931 ABSTRACT STABILIZED COPOLYMER COMPOSITION Compositions comprising an alternating copolymer of ethylene and carbon monoxide and from 0.03 to 5.0 %wt of a stabilizing compound selected from diarylamines, hydroxybenzophenones, and benzotriazoles or triazines carrying a sterically hindered phenol substituent. The composition, which show an improved long-life light stability, can be processed into articles of manufacture, such as fibers, sheets, films, laminates. containers, tubes, piping and articles having an intricate shape, using conventional processing techniques, such as melt-spinning, extrusion, coextrusion, blow-moulding, compression-moulding, injection-moulding and solid phase pressure forming.
