    • A treatment method for polythiol compounds used in thiol-ene formulations, especially formulations employing norbornene resins, significantly improves cure speed retention on aging of thiol-ene formulations which include hydroxylamine salts, such as N-nitrosoarylhydroxylamine aluminum salts, as shelf-life stabilizers. The treatment comprises contacting the polythiol with an amphoteric treating agent selected from the group consisting of silicated magnesium oxide, magnesium oxide, magnesium hydroxide, calcium oxide, calcium hydroxide, barium oxide, and barium hydroxide, and then separating the resin from the treating agent prior to mixture with a polyene to form a thiol-ene composition. In formulations employing phenolic compounds having an alkenyl group in conjugation with the phenyl group thereof as shelf-life co-stabilizers the treatment method also significantly enhances the shelf-life stability of the formulation compared to formulations made from untreatedpolythiol.
    • 用于硫醇烯制剂中的多硫醇化合物的处理方法,特别是使用降冰片烯树脂的制剂,显着提高了包括羟胺盐(例如N-亚硝基芳基羟胺铝盐)作为保质期稳定剂的硫醇 - 烯制剂老化时的固化速度保持。 处理包括使多硫醇与选自硅酸镁,氧化镁,氢氧化镁,氧化钙,氢氧化钙,氧化钡和氢氧化钡的两性处理剂接触,然后将树脂从处理剂中分离出来 与多烯混合以形成硫醇 - 烯组合物。 在使用具有与其苯基缀合的烯基的酚类化合物作为保质期共稳定剂的制剂中,与未经处理的聚硫醇制备的制剂相比,处理方法也显着提高了制剂的保质期稳定性。

    • Resin compositions useful for filament winding applications comprising an epoxy component including at least one polyepoxide resin curable by heat, an olefinically unsaturated monomer component including at least one polyolefinically unsaturated monomer curable by actinic radiation, at least one photoinitiator, at least one organic peroxide, and a heat activated curing agent. The compositions have a viscosity less than about 2000 centipoise (cps) and are capable of retaining this viscosity for at least about 2 hours at a temperature of from about ambient temperature to about 60 DEG C. The resin compositions may further include a cyanate ester component. The cyanate ester resin compositions have a viscosity less than about 2000 cps and are capable of retaining this viscosity for at least about 6 months at about ambient temperature. The resins are capable of being immobilized by actinic radiation exposure and further heat cured without substantial resin drip. One or more organic peroxides are employed, selected from the group of organic peroxides having 10 hour decomposition half lives at temperatures of from about 50 DEG C to less than about 104 DEG C. Also, fiber resin composites comprising fiber substrates impregnated with the dual-curing resin compositions. Also the process for coating fiber substrates with the dual-curing resin compositions is disclosed.
