Novel complex-forming polymers are provided having at least one aryl group carrying a complex-forming moiety of general formula
which can be prepared by contacting a compound of general formula
with a metalating agent, followed by reaction of the metalated compound with either
A.1. at least one vinylbenzyl halide, and subsequently
2. polymerizing the reaction product of A.1. or
B. a halomethylated polystyrene polymer;
wherein each R individually is H, or both R's together form a group -CH=CH-; R¹ is H or an alkyl, R² is H, an alkyl, a vinylbenzyl group or a group
R¹ and R² together form a group -(CH₂)n- wherein n is an integer in the range of from 2 up to and including 6; R³ is an alkyl, alkoxy, phenyl, phenoxy, alkylthio or phenylthio group; R⁴ is an alkyl group, or a cycloaliphatic group having from 3 to 7 carbon atoms having at least one hydrogen on the α-carbon atom; p and q are integers from 0 up to and including 2 and from 0 up to and including 3, respectively; -CR¹(R²)-CH₂- and/or R⁴ are linked to a carbon atom which occupies the ortho- or para-position with respect to the nitrogen atom in the heterocyclic aromatic ring. The products are hydrolytically stable and may be used e.g. as polymeric ligands, as such, or e.g. complexed with selected metal compounds.

与金属化剂接触,然后将金属化的化合物与以下任一反应
A.1. 至少一种乙烯基苄基卤化物,然后
聚合 A.1. 的反应产物,或
B. 卤甲基化聚苯乙烯聚合物;
其中每个 R 单独为 H,或两个 R 共同形成一个基团 -CH=CH-; R¹ 为 H 或烷基,R² 为 H、烷基、乙烯基苄基或基团
R¹ 和 R² 共同形成一个基团-(CH₂)n-,其中 n 是 2 至 6(包括 6)的整数;R³ 是烷基、烷氧基、苯基、苯氧基、烷硫基或苯硫基;R⁴ 是烷基,或具有 3 至 7 个碳原子且在α-碳原子上至少有一个氢原子的环脂族基团;p和q分别为0至2(包括2)和0至3(包括3)的整数;-CR¹(R²)-CH₂-和/或R⁴与一个碳原子相连,该碳原子相对于杂环芳香环中的氮原子处于正位或对位。产品具有水解稳定性,可用作聚合物配体,或与特定金属化合物络合。
