    摘要: Radiation-curable coating compositions particularly adapted to reduce the adhesion of the radiation-cured coatings to glass optical fibers (and thereby enhance strippability) are disclosed. These comprise a radiation-curable polyethylenic organic compound and from about 2% to about 20% of the coating composition of an organic polysiloxane carrying a plurality of hydroxy-terminated groups which are joined to some of the silicon atoms in the polysiloxane chain by a carbon-to-silicon bond. The polysiloxane reduces the adhesion of the radiation-cured coating to the glass surface of the fiber. Ultraviolet cures using acrylates as the ethylenic group are preferred.

    摘要: An improved stereolithographic process is provided in which the formation of a thin walled three-dimensional object in a reservoir of liquid ultraviolet-curable ethylenically unsaturated material using a support is positioned immediately beneath the upper surface of the liquid reservoir with that upper surface being exposed to ultraviolet light in a pattern to solidify the liquid at and near the upper surface in a series of cross-sections of the desired three-dimensional object, one atop the other. In this way there is formed a series of superposed layers which adhere to one another to build the desired three-dimensional object within the liquid reservoir. The improvement comprises, stopping the exposure at any portion of the surface in the formation of said layers and then repeating the exposure at least once again in the production of each surface layer so that the strength and solvent resistance of the formed object are increased and its distortion is minimized. The ultraviolet exposure of each surface layer is preferably carried out as a series of rapid repeated scans of a computer-directed focused laser.

    摘要: A stereolithographic method which employs an ultraviolet-curable liquid composition adapted to cure rapidly to a lightly cross-linked solvent-swellable three-dimensional complexly-shaped polymeric thin-walled element constituted by heat-softenable solid polymer upon exposure to ultraviolet dosage in the range of about 0.1 to about 10 Joules per square centimeter and which possesses reduced distortion comprises, from 20 to 80 weight percent, of a resinous polyacrylate or polymethacrylate dissolved in a combination of 10 to 45 weight percent of a liquid polyacrylate or polymethacrylate, which is preferably trifunctional, and 10 to 45 weight percent of liquid N-vinyl monomer, preferably N-vinyl pyrrolidone. Thus, the weight ratio of polyacrylate: polymethacrylate: N-vinyl monomer is about 1:2:2 to about 8:1:1. One of the foregoing polyacrylates or polymethacrylates is a polyacrylate and the other is a polymethacrylate so that good cure speed is accompanied by good distortion resistance. In the method, a reservoir of the liquid composition is established and its exposed surface is irradiated to solidify the surface and build up a thin-walled element which is removed from the reservoir, drained of liquid adhering thereto and cured.

    摘要: The reaction product of an adduct of an ethylenically unsaturated monohydric alcohol, such as 2-hydroxyethyl acrylate, with an organic diisocyanate in which one of the two isocyanate groups is more strongly reactive than the other, such as isophorone diisocyanate, is reacted with a phenoxy resin in solvent solution. The alcohol is used in a molar excess of at least about 3% up to 30% to insure the absence of any significant proportion of unreacted diisocyanate. The phenoxy resin which is reacted with is a high molecular weight hydroxy functional polyether having a number average molecular weight above 10,000 and an hydroxy functionality in the range of from about 20 to about 300. The adduct is used in an amount to introduce about 1.5 to about 20 ethylenically unsaturated groups per molecule of the polyether, and the reaction is continued to substantially eliminate unreacted isocyanate functionality. These unsaturated products are useful in electron beam coating compositions, especially in combination with unsaturated liquids which lower the glass transition temperature. They can also be used in combination with acrylate-terminated polyurethanes to provide films having greater handleability prior to cure.
