METAL COMPOSITES AND COMPOUND USEFUL FOR PREPARATION THEREOF

摘要

A high-molecular compound having a molecular weight of 5×102 to 1×107, which comprises structural units represented by general formula (P-a). In general formula (P-a), Ar2 is an optionally substituted aromatic group; R2 is a direct bond or an organic group wherein only oxygen may be contained as heteroatom; E is a heteroatom; R3 is a monovalent hydrocarbon group or a hydrogen atom; mt and nt are each independently an integer of 1 or more; lt is an integer of 1 to 3; multiple R3s, Es and lts may each be the same or different from each other; when multiple mts are present, the mts may be the same or different from each other; and when multiple groups in the parentheses with mt or nt are present, the multiple groups may be the same or different from each other.
