    摘要： Novel catalyst systems in cationically curable compositions provide colorless cationically cured compositions with improved degree of cure and thermal stability. The curable composition comprises at least one cationically curable monomer and a curing agent comprising Photocurative A or Photocurative B. Photocurative A comprises an effective amount of an accelerating photochemically active salt comprising a photochemically active cation and an accelerating anion, and an effective amount of an inhibiting non-photochemically active salt comprising a non-photochemically active cation and an inhibiting anion. Photocurative B comprises an effective amount of an inhibiting photochemically active salt comprising a photochemically active cation and an inhibiting anion, and an effective amount of an accelerating non-photochemically active salt comprising a non-photochemically active cation and an accelerating anion. The inhibiting and accelerating salts in photocuratives A and B are defined by photo differential scanning calorimetry (pDSC) and thermal differential scanning calorimetry (tDSC). The compositions are useful, for example, as optically colorless or low color coatings, adhesives, encapsulants, and sealants for optical and electronic applications.

    摘要： A composition of matter includes a polymerizable mixture comprising 1 to 99 weight percent of a first monomer and an initiator therefor, the first monomer being one of 1) at least one free-radically polymerizable monomer or 2) at least one cyanate ester monomer, and 99 to 1 weight percent of a second monomer and an initiator therefor, the second monomer being the member of 1) or 2) that is not selected as the first monomer, wherein the curative for the cyanate ester is a transition metal-containing organometallic compound curing agent and the curative for the free-radically polymerizable monomer is a free-radical generating curing agent or a transition metal-containing organometallic compound. The polymeric mixtures are useful, for example, in applications requiring high performance, such as high temperature performance; in composites, particularly structural composites; structural adhesives; vibration damping materials; electronic applications such as printed wiring boards, semiconductor encapsulants and electronic adhesives; photoresists; injection molding and prepregs; protective coatings; tough self-supporting films; and high performance binders. In addition, a curable composition comprising two partially polymerized mixed syrups of ethylenically unsaturated monomers is provided. These compositions are useful as the precursors for vibration damping materials. Further, a curable composition including (1) an ethylenically unsaturated monomer or (2) an ethylenically unsaturated monomer and a cyanate ester monomer, and certain organometallic neutral compounds is useful in the graphic arts.
