Polymers with low gel content and enhanced gas-fading
 
Zahalka et al of Chemtura Corporation, Connecticut, developed a polymer stabilizing composition comprising a sterically hindered phenol and a phosphite that provides low gel content and enhanced resistance to gas-fading. The stabilizer composition is particular useful for stabilizing polyethylene homopolymers and copolymers, such as linear low density polyethylenes produced from metallocene catalyst. The sterically hindered phenol is selected from the group consisting of 1,3,5-tris-(4-tert-butyl-3-hydroxy-2,6-dimethylbenzyl)isocyanurate, 1,3,5-tris-(3,5-dicyclohexyl-4-hydroxybenzyl)isocyanurate, 1,3,5-tris-(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanurate,1,3,5-tris(4-t- -butyl-3-hydroxy-2,6-dimethylbenzyl)-1,3,5-Triazine-2,4,6-(1H,3H,5H)-trion- e, and 1,3,5-tris-(3,5-di-tert-butyl-4-hydroxybenzyl)-2,4,6-trimethylbenze- ne. The phosphite preferably is a liquid phosphite composition comprising two or more alkylated aryl phosphites. (RDC 6/7/2012)
