摘要： A treatment method for polyene resins used in thiol-ene formulations, especially norbornene resins, significantly stabilizes thiol-ene compositions made from batches of polyene resin which otherwise give compositions with poor dark stability. The treatment comprises contacting the polyene with an amphoteric treating agent selected from the group consisting of silicated magnesium oxide, basic aluminum oxide, silica gel, 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 polythiol to form a thiol-ene composition. The treatment method significantly reduces ionic content in polyene resins, particularly chloride ion but also sodium and potassium ions. Consequently, treatment is also beneficial with polyene resins which do not produce substantial dark stability problems. Reduction of the ionic content of the resin is desirable to produce cured thiolene polymers with low electrical conductivity and low corrosiveness.

摘要： 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 untreated polythiol.
