Abstract:
A composition formed by combining components comprising:a) a polyolefin; b) a first phosphite, which is an arylalkyl diphosphite having a formula, wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 can be the same or different and are selected from the group consisting of hydrogen and straight-chained or branched, cyclic or acyclic, aromatic or aliphatic, and mixed aliphatic, aromatic, and/or cycloaliphatic organic radicals having from about 1 to about 20 carbon atoms per radical;c) a second phosphite selected from the group consisting of: (i) a second arylalkyl diphosphite of formula (I), wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 can be the same or different and are selected from the group consisting of hydrogen and straight-chained or branched, cyclic or acyclic, aromatic or aliphatic, and mixed aliphatic, aromatic, and/or cycloaliphatic organic radicals having from about 1 to about 20 carbon atoms per radical, which is different from said first arylalkyl diphosphite and (ii) a triarylphosphite having a formula, wherein R1, R2, R3, R4, and R5 are selected from the group consisting of hydrogen and straight-chained or branched, cyclic or acyclic, aromatic or aliphatic, and mixed aliphatic, aromatic, and/or cycloaliphatic organic radicals having from about 1 to about 20 carbon atoms per radical;d) a hindered phenol; and e) water.
