Abstract
The corrosion tendencies of polymers of 4-methyl-1-pentene, when combined with tris-(3,5-ditert-butyl-4-hydroxybenzyl)isocyanurate and bis(2,4-ditert-butyl)pentaerythritol diphosphite are reduced. Optionally, metal stearates and/or poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-5-triazine-2,4-diyl][2,2,6,6-tet ramethyl-4-piperidyl)imino]hexamethylene[2,2,6,6-tetramethyl-4-piperidyl)im ino]] can be added to further reduce the polymer corrosion tendencies.
