Novel perfluoropolyether derivatives are described which are obtained from perfluoropolyethers having a carboxyl group at one or both ends and monoamines or diamines. The derivative is useful as a lubricant owing to its significantly improved lubricity. The lubricity is shown under severe high or low temperature and humidity conditions over a long term. The derivative is especially useful as a lubricant for magnetic recording mediums of the coating and metal thin film types.
本文描述了新型全氟聚醚衍生物,该衍生物由一端或两端带有羧基的全氟聚醚和单胺或二胺制成。这种衍生物的润滑性能显著提高,可用作润滑剂。这种润滑性可在严酷的高温或低温和潮湿条件下长期保持。该衍生物特别适用于涂层型和金属薄膜型磁记录介质的润滑剂。
