Abstract
A lubricating composition for the manufacture and surface treatment of metallic pipe, wire, sheet and so on contains a high molecular polyester or polyurethane having a weight average molecular weight of not less than 10,000 which is the product of reacting a polyalkylene oxide compound formed by on addition-polymerization of an ethylene oxide-containing alkylene oxide and an organic compound having two active hydrogen groups with a polycarboxylic acid or the corresponding anhydride or lower alkyl ester to form the polyester or with a diisocyanate to form the polyurethane. The composition forms a highly lubricating film, and since this film is readily soluble in water and organic solvents, residues of the lubricating composition on the treated surface can be easily dissolved off after metal working.
