  The invention is based on the discovery that adhesive compositions containing certain low-viscosity, mono-ethylenically unsaturated monomers have surprisingly good cure parameters, resulting in very little weight loss upon cure. Many of these monofunctional monomers used alone or in combination with other monofunctional monomers described herein have high glass transition temperatures when cured. Moreover, since these monomers are monofunctional the crosslink density of the adhesive composition does not increase (relative to multi-functional monomers), which in turns results in lower stress, lower modulus adhesive compositions. As such, these monomers are useful in a variety of thermoset adhesive compositions, such as for example, die attach adhesive compositions.

  该发明是基于发现，含有某些低黏度、单乙烯不饱和单体的粘合剂组合物具有惊人的固化参数，固化后重量损失非常小。其中许多单官能单体单独使用或与本文所述其他单官能单体组合使用时，在固化后具有较高的玻璃转移温度。此外，由于这些单体是单官能的，粘合剂组合物的交联密度不会增加（相对于多官能单体），这反过来将导致较低的应力、较低的模量粘合剂组合物。因此，这些单体在各种热固性粘合剂组合物中非常有用，例如，封装粘合剂组合物。

  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.
