Abstract: The present invention relates to blow molded multilayer hollow articles and a coextrusion blow molding process for the production of said multilayer hollow articles, made of thermoplastic polymers and characterized by a specific visual effect. More in particular, the present invention relates to multilayer hollow articles and a coextrusion blow molding process for the production of said multilayer hollow articles, wherein at least one layer is a continuous layer with a uniform degree of thickness and at least one layer is a discontinuous or a non-uniform continuous layer with varying degree of thickness, which results in a specific surface pattern and/or visual color effect.

Abstract: The invention relates to the use of an additive as oxygen scavenger in a plastic material, wherein (a) the plastic material is a polyester, a polyolefin, a polyolefin copolymer or a polystyrene, and the additive (b) is a light stabilizer and optionally a transition metal compound.

Abstract: The invention relates to use of an additive as oxygen barrier in a plastic material wherein (a) the plastic material is a polyolefin, a polyolefin copolymer or a polystyrene, and the additive is (b) and optionally (c): (b) a compound of formula (I); wherein Ra represents C7-C20 alkyl, C6-C10 aryl, C4-C10 heteroaryl, wherein the heteroatoms are N, O and/or S, (C2-C6)-alkenylen-(C6-C10) aryl, C1-C6-alkylen-C6-C10-aryl, the aryl and heteroaryl radicals optionally being substituted by: hydroxyl, C1-C6-alkyl, C1-C6 alkoxyl, C6-C10 aryloxy, halogen, cyano, nitro, C6-C10-aryl, di(C1-C6)alkylamino, (C1-C6)alkylthio, C6-C10-arylthio, ?O, ?S, SO3H, SO2NR1R2, CO2R3, CONR1R2, NHCOR4, CO—C6-C10-aryl or a combination thereof, wherein R1, R2, R3, R4 are the same or different and independently represent hydrogen or Rb represents a group selected from the moieties of formula (II), (III), (IV), (V), (VI) and (VII); wherein each Rc can be the same or different and independently represents hydrogen, C1-C20
