DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) In the photooxidn. of polypropylene [9003-07-0] films, 4-hydroxy-1,2,2,6,6-pentamethylpiperidine [2403-89-6] gave a synergistic effect with UV-531 (2-hydroxy-4-n-octyloxybenzophenone) [1843-05-6], an additive effect with Irgastab 2002 [nickel(3,5-di-tert-butyl-4-hydroxybenzyl phosphonate monoethylate)] [30947-30-9], and a weak antagonistic effect with UV-327 [2-(2'-hydroxy-3',5'-di-tert-butylphenyl)-5-chlorobenzotriazole] [3864-99-1]. .

Photo-stabilization action of metal chelate stabilizers in polypropylene

Photo-stabilization action of metal chelate stabilizers in polypropylene. Part VII. Additive interactions. Allen, Norman S.; Chirinos-Padron, Alfonso; Appleyard, John H. (John Dalton Fac. Technol., Manchester Polytech., Manchester M1 5GD, UK). Polym. Degrad. Stab., 6(3), 149-76 (English) 1984. CODEN: PDSTDW. ISSN: 0141-3910. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) The interactions of 3 metal chelates Cyasorb UV 1084 [14516-71-3] and Irgastab 202 [30947-30-9] and Irganox 1425 [65140-91-2] with other com. additives, in the stabilization of polypropylene [9003-07-0] film, are examd. using normal and 2nd-order deriv. UV and IR spectroscopic techniques. The obsd. behavior is dependent on the particular additive, the processing history of the polymer and the metal chelate concerned, and is therefore highly complex. All 3 chelates show antagonism with a hindered piperidine, Tinuvin 770 [52829-07-9], in unprocessed polymer, whereas one of the chelates behaves synergistically with this additive in processed samples. The chelates also show antagonism with a primary antioxidant, Goodrite 3125 [34137-09-2], whereas, with a secondary antioxidant, Weston 618 [3806-34-6], their behavior is synergistic in both unprocessed and processed polymer.There are some commonly used reagents with their cas registry numbers 34137-09-2 and 14516-71-3 in this article. Two of the chelates show synergism with (Cyasorb UV 531) [1843-05-6], the remaining chelate showing antagonism. Mixts. contg. a 3-additive system show a more complex behavior. The results are attributed to hydroperoxide decompn., inhibition, stabilizer dispersion, UV stability and additive compatibility. .
