The invention provides a stabilizer for high polymers containing as an effective component a mixture comprising at least one member selected from phenolic type compounds of formula (I),
wherein R, represents a C1-C9 alkyl group, R2 represents a C1-C3 alkyl group, R3 represents a hydrogen atom or a methyl group, x represents an integer of 2 to 6, y represents an integer of 1 to 10, and A represents a di- to hexahydric carboxylic acid residue, but it may be simply a single bond when x is 2, and at least one member (I I) selected from the group consisting of sulfur-containing compounds of formula (11-1),
wherein R4 represents a C4-C20 alkyl group, and those of formula (II-2),
wherein R5 represents a C3-C18 alkyl group, and R6 and R7 are selected independently from a hydrogen atom and C1-C6 alkyl groups. Preferably the weight ratio of phenolic type compound (I) to sulfur-containing compound (II) is 1 to 0.5-15, preferably 1 to 1-10, most preferably 1 to 2-6. The invention also provides high polymers containing the stabilizer.
本发明提供了一种高聚物稳定剂,其有效成分是由至少一种选自式(I)酚类化合物的混合物组成、
其中 R 代表 C1-C9 烷基,R2 代表 C1-C3 烷基,R3 代表氢原子或甲基,x 代表 2 至 6 的整数,y 代表 1 至 10 的整数,A 代表二水至六水羧酸残基,但当 x 为 2 时,它可以只是一个单键,以及至少一个选自式(11-1)含硫化合物组的成员(I I)、
其中 R4 代表 C4-C20 烷基,以及式(II-2)的含硫化合物、
其中 R5 代表 C3-C18 烷基,R6 和 R7 独立选自氢原子和 C1-C6 烷基。酚类化合物(I)与含硫化合物(II)的重量比最好为 1 比 0.5-15,优选 1 比 1-10,最优选 1 比 2-6。本发明还提供了含有稳定剂的高聚物。
