    摘要: Water soluble polyester-imide prepolymers are prepared (1) having 5 to 60%, preferably at least 35%, of imide moieties, (2) an excess hydroxyl content in excess of 60% and preferably more than 100%, and (3) a number average molecular weight of 600-1300. To water solubilize the prepolymers formed, there are added amines, preferably tertiary amines. The products are useful as wire enamels. To enhance the thermoplastic flow of the enamel, there are added organic titanates.

    摘要: 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.
