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-tetramethyl-4-piperidyl)imino]hexamethylene]2,2,6,6-tetramethyl-4-piperidyl)imino]] can be added to further reduce the polymer corrosion tendencies.
当 4-甲基-1-戊烯聚合物与三-(3,5-二叔丁基-4-羟基苄基)异氰脲酸酯和双-(2,4-二叔丁基)季戊四醇二亚磷酸酯结合使用时,其腐蚀倾向会降低。可选择添加金属硬脂酸盐和/或聚[[6-[(1,1,3,3-四甲基丁基)氨基]-5-三嗪-2,4-二基][2,2,6,6-四甲基-4-哌啶基)亚氨基]六亚甲基]2,2,6,6-四甲基-4-哌啶基)亚氨基]],以进一步降低聚合物的腐蚀倾向。
