Abstract: A liquid composition used for dissolving fingernail polishes contains three non-miscible liquid phases which, when the composition is left still, are superimposed one on the other. The upper phase is oily. The intermediate phase is the solvent phase and contains solvents immiscible with water. In addition to a tri-phase composition also a bi-phase composition is described. The solvents are a mixture of methyl acetate and tert-butyl acetate.

Abstract: A novel polymer-coated carbon, metal, or ceramic substrate is coated with an aromatic polysiloxane liquid coating solution polymerized to have non-linear, ladder silicon to oxygen bonding. A carbon, metal, or ceramic layer or substrate coated with the aromatic polysiloxane liquid polymer provides enhanced thermal protection and oxidative stability. The novel aromatic polysiloxane liquid polymer-coated carbon, metal, or ceramic substrate preferably includes a non-linear, ladder aromatic polysiloxane polymer-coated carbon, metal, or ceramic substrate such as provided by polyphenylsiloxane polymer having the general formula R.sub.n SiO.sub.(4-n)/2, wherein R comprises phenyl radical, and n has an average value of about 0.95 to 1.05.

Abstract: When a dispersion of oxide ceramic particles in certain volatile organic solvents is mixed with less than about 2 percent by weight (based on the weight of particles) of an oligomeric polysiloxanol dispersant, and the dispersion allowed to settle, the oligomer provides a multiplicity of OH groups, many of which are available for interactive bonding to the surfaces of the particles. The net result is that the particles settle more slowly; also, the sediment has a density higher than that of sediment from a dispersion of the same particles in the same solvent mixed with the monomeric silane from which the oligomer was formed. Exceptionally dense and strong "tape", for making sintered circuitized multilayered ceramic structures, is produced by capitalizing on this phenomenon. The effectiveness of the oligomer is predicated upon the prehydrolysis of the siloxane, prior to forming the dispersion.

Abstract: The present invention relates to a window assembly including a transparent sheet having a layer of retention material adhered thereto, and a method and apparatus for producing such a window assembly. The apparatus includes at least two cooperating mold sections having facing surfaces defining a chamber for receiving the transparent sheet which can be shaped for use as a vehicle backlight. A seal is positioned about a periphery of a predetermined area on a surface of the transparent sheet on which the film is to be formed. The seal, the predetermined surface area of the transparent sheet and the mold define a forming cavity into which is injected a thermosetting polyurethane material. The material is at least partially cured in the cavity. Thereafter, the window assembly is removed from the mold chamber with a polyurethane retention shield adhered to the predetermined surface area.

Abstract: An improved method of preparing a glass release surface useful in the manufacture of anti-lacerative window assemblies is disclosed. The glass surface is treated with a perfluorosilane such as (Heptadecafluoro-1,1,2,2-Tetrahydrodecyl)-1-Trichlorosilane, and thereafter may be easily released from the polyurethane layer of an anti-lacerative window assembly. The release agent (Heptadecafluoro-1,1,2,2-Tetrahydrodecyl)-1-Trichlorosilane is particularly useful under severe laminating conditions such as high temperature and pressure over a long period of time. Its use imparts excellent optical properties to the polyurethane layer.

Abstract: An improved method of preparing a glass release surface useful in the manufacture of anti-lacerative window assemblies is disclosed. The glass surface is treated with octadecyltriethoxysilane, and thereafter may be easily released from the polyurethane layer of an anti-lacerative window assembly. Use of the octadecyltriethoxysilane parting agent enables excellent optical properties to be imparted to the polyurethane layer.

Abstract: This invention relates to polymer/polyols prepared from an ethylenically unsaturated monomer or a mixture of such monomers and characterized by the utilization, in the preparation thereof, of certain preformed stabilizers tailored to the monomer system employed, a method of preparing such polymer/polyols, and to the preformed stabilizers themselves. In general, the stabilizer, compatible with the polyol portion of the polymer/polyol, comprises a copolymer of an anchor portion consisting of an ethylenically unsaturated monomer or mixture of such monomers and a solvatable portion consisting of a propylene oxide polymer having a number average molecular weight of at least 800. The resulting polymer/polyols are stable, fluid, essentially free from scrap and seeds as produced and contain relatively small polymer particles. In accordance with one aspect of this invention, the polymer particles are essentially spherical in shape.

The novel compositions are highly useful in the production of polyurethane products.

Abstract: Novel high resilience (HR) urethane foams are prepared from tolylene diisocyanate and novel polymer/polyol compositions made with acrylonitrile and vinylidene chloride monomers. The acrylonitrile:vinylidene chloride-polymer/polyol compositions enhance the load-bearing properties and decrease the flammability of HR foams made with them.
