Homogeneously dispersed solid reaction promoters having an average particle size from 0.01 &#x3bc;m to 500 &#x3bc;m are disclosed for preparing curable mixtures of at least one Michael donor and at least one Michael acceptor. The resulting curable mixtures are useful as coatings, adhesives, sealants and elastomers.

Method for promoting Michael addition reactions

Functional mixtures and polymer compositions are provided, each comprising at least one multi-functional Michael acceptor, at least one multi-functional Michael donor, in which at least 20% of either the donor or acceptor or a combination of the donor and acceptor is derived from bio-based materials and at least one catalyst.

Biomass based Michael addition compositions

A functional mixture is provided that comprises at least one multi-functional Michael acceptor, at least one multi-functional Michael donor, and at least one weakly basic catalyst.

Michael addition compositions

A method is provided for bonding substrates using a homogeneous fluid and a polymerizing condition. Also provided are composite articles formed by such a method. The composite articles show improved adhesion between the substrates and the adhesive composition over a wide range of temperatures.

High performance adhesive

Provided are improved coatings, polymeric dispersions, and polymeric composites, which include crosslinked polymeric nanoparticles (hereafter 'PNPs'). Also provided are methods for forming improved coatings, polymeric dispersions, and polymeric composites, which include PNPs. The PNPs have polymerized units of at least one multi-ethylenically-unsaturated monomer have a mean diameter of from 1 to 50 nanometers. PNPs having polymerized units of at least one multi-ethylenically-unsaturated monomer and at least one surface-active monomer are also provided.

Coating and coating composition

A method of preparing a cured laminate employing electron beam radiation is provided. The cured laminate is prepared from an uncured laminate including a prepolymer composition containing oligomer, tackifying resin, and optionally, monomer. Also provided are a prepolymer composition and an article including the cured laminate prepared by the method of this invention. The method is useful for preparing cured laminates such as flexible laminates for food packaging.

Method for preparing a laminate

A method of preparing a curable coating and a method of curing the curable coating are disclosed. The curable composition from which the curable coating is prepared may be applied to the surface of a substrate in neat form or in aqueous medium to produce the coating. Curing of the curable coating may be accomplished by chemical generation of free radicals, by electrochemical generation of free radicals, by electron beam, by photochemical generation of free radicals, or by other electromagnetic irradiation.

Continuous polymerization process and products therefrom

The present invention relates to an oligomer with a semi-telechelic nitrogen-functionality and at least one ethylenic unsaturation pendant to the backbone of the oligomer. In addition, a process is provided to prepare the semi-telechelic nitrogen-functional oligomer. The semi-telechelic nitrogen-functional oligomer is useful as a dispersant for pigments in radiation curable formulations.

Semi-telechelic nitrogen-functional oligomer

The present invention provides a method of preparing semi-wet pressed green bodies having improved wet strength. The wet strength of the semi-wet pressed green bodies is increased by the addition of at least one polymeric binder having a molecular weight greater than 50,000 comprising, as polymerized units, at least 10 percent of one or more monoethylenically unsaturated acids, salts, or anhydrides, and further comprising at least one hydrophobe per polymeric chain on average. The present invention further provides semi-wet pressed green bodies, having improved wet strength, made from the above method. In one embodiment, the polymeric binder increases the wet strength of ceramic green bodies. In another embodiment, the polymeric binder increases the wet strength of metallurgic green bodies. In another embodiment, the polymeric binder increases the wet strength of cermet green bodies.

Process for preparing green bodies

The present invention is directed to producing a luminescent screen used in a cathode ray tube (CRT) suitable for monochromatic or chromatic images, such as, those utilized in televisions, computers or data monitoring equipment, which require CRTs. The method of the present invention produces an ablative layer of the luminescent screen having a smooth surface with reduced surface distortions, such as, streaks and waviness, which are typically produced by conventional coating processes. When a reflective aluminum film is deposited on such a smooth ablative layer, the reflective aluminum film is also provided with a smooth surface, since it typically conforms to the underlying smooth surface of the ablative layer. As a result, CRT images having reduced distortions are produced. The method of the present invention further provides for enhancing the brightness of CRT images, which results from utilizing low ash producing polymers in the ablative layer and the binder of a luminophor layer of the luminescent screen. The method of the present invention further provides for combining the step for volatilizing of the ablative layer and the binder in the luminophor layer with the step for cementing of the face plate of CRT with the cone of CRT, without adversely affecting the quality of the hermitic seal between the face plate and the cone.

Method for producing luminiscent screen

A reticulated ceramic product is provided having from about 5 to about 95 percent, preferably from about 10 to about 90, percent of the total porosity attributable to mesopores. Reticulated ceramic products provided include silicon oxide, aluminum oxide, zirconium oxide and ruthenium oxide. Reticulated ceramic products are prepared using a porous solid matrix as a template. The reticulated ceramic products are useful as chromatographic media, catalysts and adsorbents.
