Insulated wire |
摘要 |
An insulated wire having excellent heat resistance, abrasion resistance and flexibility can be prepared by coating on an electric conductor directly or via another insulating material a polyamide-imide resin composition prepared by reacting an aromatic diisocyanate and a tricarboxylic acid anhydride in the presence of a basic solvent while adjusting the resin content at 40% by weight or more, and adding to the reaction system a lactam in an amount of 0.1 to 1.0 mole per mole of the aromatic diisocyanate, and if necessary, an alcohol and/or an oxime in an amount of 0.01 to 0.5 mole per mole of the aromatic diisocyanate before, during or after the above-mentioned reaction to mask terminal functional groups and to make the reduced viscosity of the composition 0.1 to 0.27, and baking the resin composition.
