Stabilizer compositions for halogen-containing polymers are provided composed of a β-diketone having the formula:
wherein:
R1 is selected from the group consisting of hydrogen, hydrocarbon groups having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR1, ester COOR,, alkyl and alkoxycarbonyl alkyl having from one to about eighteen carbon atoms, and
R2 is selected from the group consisting of hydrogen; hydroxyl; hydrocarbon having from one to about eighteen carbon atoms and such hydrocarbon groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR,, ester COOR1, alkyl and alkoxycarbonyl having from one to about eighteen carbon atoms; and if Z is R2 or n is 1 to 3, then no more than one R2 is hydrogen;
one R1 and one R2 or two R2 may be linked together as an alkylene group to form a cyclic or ring structure;
n is a number from 0 to 3; and
Z is selected from the group consisting of R2 and a polyvalent linking radical selected from the group consisting of a direct linkage between the
polyvalent hydrocarbon R3;
wherein:
R3 is a polyvalent hydrocarbon group having from one to about eighteen carbon atoms;
R4 and R5 are selected from the group consisting of hydrogen and hydrocarbon groups having from one to about eighteen carbon atoms; and R4 and R5 may be linked together as an alkylene to form a cyclic or ring structure;
X is -0- or -S-;
m is 0 or 1; and
R6 is selected from the group consisting of hydrogen, hydrocarbon having from one to about eighteen carbon atoms, and -R3-;
as well as metal and organotin enolate salts thereof; and a hydrotalcite having the general formula:
wherein
x is a number from 0 to 0.5;
A is CO3= or S04=, and
m is a number representing the number of H20 in the molecule.
The stabilizer compositions are effective in enhancing the resistance to deterioration by heat and light of halogen-containing polymers and especially polyvinyl halide resins. The β-diketone and hydrotalcite in these compositions exhibit a synergistic stabilizing effectiveness superior to either alone in like amount.
提供了用于含卤聚合物的稳定剂组合物,该组合物由具有以下式子的 β-二酮组成:

R1 选自氢、具有 1 至约 18 个碳原子的烃基和被 1 个或多个选自卤素、羟基、烷氧基 OR1、酯 COOR、具有 1 至约 18 个碳原子的烷基和烷氧羰基烷基的基团取代的烃基组成的组,和
R2 选自由下列组成的组:氢;羟基;具有 1 至约 18 个碳原子的烃基,以及被 1 个或多个选自由下列组成的组的基团取代的烃基:卤素、羟基、烷氧基 OR、酯 COOR1、烷基和具有 1 至约 18 个碳原子的烷氧羰基;如果 Z 是 R2 或 n 是 1 至 3,则不超过一个 R2 是氢;
一个 R1 和一个 R2 或两个 R2 可作为亚烷基连接在一起,形成环状或环状结构;
n 是 0 至 3 的数字;以及
Z 选自 R2 和多价连接基组成的组,多价连接基选自以下组成的组
多价烃 R3;
其中
R3 是具有 1 至约 18 个碳原子的多价烃基;
R4 和 R5 选自氢和具有 1 至约 18 个碳原子的烃基;R4 和 R5 可作为亚烷基连接在一起,形成环状或环状结构;
X 是-0-或-S-;
m 是 0 或 1;以及
R6 选自由氢、具有 1 至约 18 个碳原子的烃和-R3-组成的组;
及其金属盐和有机锡烯酸盐;以及通式为
其中
x 是 0 至 0.5 的数字;
A 是 CO3= 或 S04=,以及
m 是代表分子中 H20 数量的数字。
这些稳定剂组合物能有效提高含卤聚合物,特别是聚卤乙烯树脂的耐热和耐光劣化性能。这些组合物中的β-二酮和氢滑石具有协同稳定效果,其效果优于单独使用相同数量的其中一种。
