| abstract |
The invention relates to a stabilized polyolefin composition, which composition is stabilized against deterioration caused by contact with heavy metals and improved in coloration properties. This is achieved by blending a polyolefin with: (A) a phenolic compound represented by the formula (I), <IMAGE> (I) wherein R1 represents a C1-C3 alkyl group, (B) a metal deactivator having one or more <IMAGE> groups in the side chain, and (C) a sulfur-containing compound represented by the formula (II-1), (II-2), (II-3) or (II-4): <IMAGE> (II-1) wherein R2 represents a C4-C20 alkyl group, <IMAGE> (II-2) wherein R3 represents a C4-C20 alkyl group, <IMAGE> (II-3) wherein R4 represents a C3-C18 alkyl group, and R5 and R6 independently represent a hydrogen atom or a C1-C6 alkyl group, <IMAGE> (II-4) wherein R7 represents a C3-C18 alkyl group. |
