Abstract: A novel gas phase process for the production of 1,1-dichloro-1-fluoroethane from vinylidene chloride and hydrogen fluoride is provided. The process is charac­terized by high conversion of vinylidene chloride to product, with a high selectivity for 1,1-dichloro-1-fluoro­ethane. The process may also be operated to selectively form 1-chloro-1,1-difluoroethane. Few volatile by-products and substantially no tar or oligomeric material is formed. Catalyst performance remains constant over extended periods of time.

Abstract: Un joint d'étanchéité à pression est utilisé pour contenir de l'hélium dans un réfrigérateur cryogénique qui utilise un ensemble d'entraînement linéaire. Un joint déformable (30) est utilisé pour assurer l'étanchéité des éléments de carter qui renferme l'unité d'entraînement linéaire de manière à réduire les fuites d'hélium. Des organes cannelés de manière concentrique (31, 32) compriment le joint en métal doux (30) sur ses côtés opposés pour former à l'intérieur des rainures d'étanchéité ayant la configuration d'un labyrinthe.

Abstract: What is described herein is a liquid U.V. stabilizer composition and process for effectively surface modifying a PVC resinous body to provide a stabilizing amount of U.V. stabilizer within the surface region of the body within a predetermined solu­tion contact time without leaving an appreciable amount of solvent therein or stabilizer on the surface of the body, and without af­fecting the surface appearance of the modified surface of the body. In one form of the invention, the U.V. stabilizer com­position comprises about 10 to 50 wt/vol%, preferably 15 to 35 wt/vol%, of a U.V. stabilizer dissolved in a mixture of methylene chloride and a liquid fluorochloro hydrocarbon. Suitably the methylene chloride component of the solvent mixture comprises about 40 to 99%, preferably about 50 to 85%, and the fluorochloro hydrocarbon component comprises about 1 to 60%, preferably about 15 to 50%, of the solvent mixture. A preferred fluorochloro hydrocarbon is 1,1,2-trifluoro-1,2,2-trichloroethylene.

Abstract: Acrylic coating resins with attached light stabilizer functional groups are provided, which resins are prepared by reacting light stabilizer hydrazides, LS-C(=O)-NR³-NH₂, with an acrylic prepolymer containing at least two different types of reactive functional groups, one of which is a hydroxyalkyl ester group and the other is carboxyl, anhydride, epoxy or isocyanate. LS is a light stabilizer moiety, e.g., of formula

wherein R³ is, e.g., hydrogen and R¹⁵ is, e.g., a direct bond. The reaction may be carried out in an inert solvent or in the bulk state.
The acrylic resins so produced are particularly useful in the stabilization of enamel or lacquer coatings and exhibit outstanding weatherability and durability. As a result of being chemically bound, the light stabilizers are resistant to loss due to volatility and extractability during typical coatings bake operations and exposure to the elements of weather.
