Self-bondable polyamides are prepared by reacting an aromatic diisocyanate or diamine with a mixture of terephthalic acid and an aliphatic dibasic acid having at least 6 carbon atoms. These self-bondable amides can also be used as topcoats for wires having basecoats of another polymer, e.g. a polyester, polyester-imide, or polyamide-imide.

A method of coating conductors with polyvinyl formal dissolved in a solvent comprising certain monoalkyl ethers of diethylene glycol and triethylene glycol or the monophenyl ether of ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol or propylene glycol. In some cases it is necessary to have a diluent such as an aromatic hydrocarbon present.
