Abstract: 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.

Abstract: 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.

Abstract: 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.
