    摘要: A heat-resistant resin composition comprised of a mixture prepared by kneading a polybutylene terephthalate resin together with a component different from said polybutylene terephthalate resin, wherein a β relaxation peak of said heat-resistant resin composition on the tan δ curve determined by the dynamic viscoelasticity measurement defined in Japanese Industrial Standard K 7244-4 appears at a temperature lower than a temperature at which a β relaxation peak of a composition composed singly of a polybutylene terephthalate appears; and said another component is dispersed in said polybutylene terephthalate resin phase in a form of particles having sizes of 1 μm or smaller.

    摘要: An insulated wire including a conductor, and an insulating film formed by coating and baking an insulating varnish on the conductor directly or via another insulation layer. The insulating varnish includes a phenolic hydroxyl group-containing polyimide resin represented by a chemical formula (1): where X is a tetravalent aromatic group composing an aromatic tetracarboxylic dianhydride residue, Y1 is a divalent aromatic group including one or more phenolic hydroxyl groups and Y2 is a divalent aromatic group not including a phenolic hydroxyl group A ratio of the number Z1 of phenolic hydroxyl groups included in Y1 of the chemical formula (1) to the number Z2 of an imide group included in the chemical formula (1) is 0.15≦Z1/Z2≦0.85.
