The invention concerns a composition for use as drier in auto-oxidizable coatings or as accelerator in unsaturated polyester resins, comprising a manganese-bearing polymer having a manganese dicarboxylate repeating unit and at least one nitrogen-containing donor ligand. Such compositions offer excellent drying performances. They ensure a strongly reduced leachability of manganese compared to that of known manganese-bearing driers.
本发明涉及一种在自动氧化涂料中用作干燥剂或在不饱和聚酯树脂中用作促进剂的组合物,该组合物由具有二羧酸锰重复单元和至少一个含氮供体配位体的含锰聚合物组成。这种组合物具有优异的干燥性能。与已知的含锰干燥剂相比,它们可确保大大降低锰的浸出率。
