  • Patent number: 6503959
    Abstract: A photocurable composition comprising (A) an &agr;-cyanoacrylate and (B) a metallocene compound comprising a transition metal of Group VIII of the periodic table and aromatic electron system ligands selected from &pgr;-arenes, indenyl, &eegr;-cyclopentadienyl. The photocurable composition may further comprise (C) a cleavage-type photoinitiator. The photocurability of the photocurable composition can be greatly improved by incorporating a cleavage type photoinitiator into the composition. Even when the composition contains a radical-polymerizable compound such as an acrylic compound, it can be rapidly cured due to the cleavage type photoinitiator contained therein. In the case where the cleavage-type photoinitiator used is a peroxide, heating can also be used to cure the composition. In the case where the cleavage type photoinitiator used is an azo compound, the composition can be foamed by regulating the addition amount of the photoinitiator or the quantity of light with which the composition is irradiated.

  • Publication number: 20020198279
    Abstract: A single component liquid heat-curable adhesive formulation that is stable at room temperature. The formulation includes from about 5 to about 70 wt % of at least one acrylate monomer, from about 5 to about 94 wt % of an acrylate oligomer, and from about 0.1 to about 10 wt % of a thermal initiator selected from the group consisting of diacyl peroxides, benzoyl peroxides and peroxy esters. A photo initiator may be included thereby rendering the stable liquid formulation to be both heat-curable and UV-curable.

  • Patent number: 6368994
    Abstract: A method for rapid polymerization, curing or a combination thereof of a polymerizable or curable composition to yield polymers and composites based on these polymers through the utilization of short wavelength microwave energy is described. The inventive method is generally applicable to the chemical transformation of any organic material that can be processed by heating. This invention also relates to specially prepared particulate polymerization curing materials which, when dispersed and irradiated in a polymerizable or curable composition, will effect rapid polymerization, curing or a combination of polymerization and curing of that composition without exceeding the decomposition temperature of the polymerizable or curable composition when the composition is exposed to microwave radiation. The polymerization agent may also be encapsulated by a material which coats the polymerization agent to prevent its premature release into the polymerizable or curable composition.
