synthesis and relevant properties of some cationic polyelectrolytes of the [x,y]-ionene type (i.e., molecules consisting of dimethylammonium charge centers interconnected by alternating alkyl chain segments containing x and y methylene groups) are described. Such hydrophobic ionenes can form intramolecular aggregates and function as micelle-mimetic agents since they mimic the key properties of traditional

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.
