Stabilized polymer composition |
摘要 |
A stabilized synthetic polymer composition comprising (1) 100 parts by weight of a synthetic polymer, (2) 0.001 to 5 parts by weight of a poly(alkylated alkenylphenol) composed substantially of monomeric units represented by the following formula (I) <IMAGE> (I) wherein R represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R1 represents an alkyl group having 1 to 18 carbon atoms; and R2 represents a hydrogen atom or an alkyl group having 1 to 18 carbon atoms; and (3) 0.001 to 5 parts by weight of an auxiliary stabilizer selected from the group consisting of polyhydric alcohol esters of alkylthioalkanoic acids, polyesters of thiodipropionic acid and organic phosphite compounds.
