  A superconducting magnet coil contains a coil of superconducting wire (2) and a cured product (3) of a curable resin composition with which the coil has been impregnated, the cured product having a thermal shrinkage factor of 1.5-0.3%, preferably 1.0-0.3%, when cooled from the glass transition temperature to 4.2 K, a bend-breaking strain of 2.9-3.9%, preferably 3.2-3.9%, at 4.2 K and a modulus of 500-1,000 kg/mm² at 4.2 K, or undergoing a thermal stress of 0-10 kg/mm² when cooled from the glass transition temperature to 4.2 K and resisting to quench during superconducting operation. It is produced by winding a superconducting wire (2) to form a coil; impregnating the coil with a curable resin composition of low viscosity which contains for example at least one epoxy resin selected from the group consisting of diglycidyl ether of bisphenol A, diglycidyl ether of bisphenol F and diglycidyl ether of bisphenol AF, all having a number-average molecular weight of 350-1,000, a flexibilizer and a curing catalyst, to obtain a curable-resin composition-impregnated coil; and heating the curable-resin-composition-impregnated coil to cure the composition.

  The solution stability of a modified bisimide resin is enhanced by partially polymerizing a mixture of a bisimide monomer and a reactive triene which contains a conjugated double bond capable of Diels-Alder reaction with the bisimide. Such partial polymerization of a bisimide with a reactive triene such as myrcene provides a modified bisimide having good solubility in an organic solvent, and particularly suitable for electrical laminating applications.
