Abstract: An improved process for producing n-butyl acrylate in high yield and high purity substantially free of acrylic acid, incorporates one or more of the following new process components in an acid-catalyzed esterification process for producing n-butyl acrylate:1. A hydrolytic recovery component, wherein heavy end adducts produced during the acid-catalyzed esterification are hydrolyzed, recovered, and recycled as valuable reactants from a hydrolytic recovery unit (HRU);2. A cracking reactor component, preferably used with the HRU, wherein additional valuable reactants are recovered and recycled after treatment in the cracking reactor; and3. A new distillative component, wherein a crude n-butyl acrylate stream is efficiently distilled in an aqueous mode through an acrylic acid separation column, thereby providing n-butyl acrylate substantially free of acrylic acid and in high yield.The first two components also are applicable to acid-catalyzed processes producing C.sub.1 to C.sub.4 alkyl acrylates.

Abstract: A miscible blend of two acrylic polymers, one of which contains a poly(1,2 -alkyleneoxy) side chain, with a soluble lithium salt yields a conducting polymer system useful in small rechargeable batteries without the need for volatile polar solvents. By employing one polymer with a glass temperature below 35.degree. C. in conjunction with control of molecular weight of both components, a flexible film may be formed by conventional thermoplastic methods. The conductive salt, preferably LiN(CF.sub.3 SO.sub.2).sub.2), may be incorporated during the polymerization which forms the acrylic polymers.

Abstract: Methods for preparing uniformly sized polymer particles comprised of multi-functional monomers such as poly(1,4-butanediol diacrylate) and poly(1,6-hexanediol diacrylate) are disclosed. The particles are of a size, uniformity, and contan physical characteristics that make them ideally suitable for use as spacers in liquid crystal display devices.

Abstract: Hydrogen cyanide or ammonia present in a gaseous stream is decomposed catalytically in the presence of oxygen at relatively low temperature by contact with carbonaceous adsorbents doped with oxides of first row transition metals, silver or lanthanide elements, preferably with cobalt, chromium, manganese, silver, and cerium, in the presence or absence of a gaseous reducing agent such as a hydrocarbon or a volatile carboxylic acid.

Abstract: The invention provides a process for reducing one or more carbonyl impurity present in a monomer of an .alpha.,.beta.-unsaturated carboxylic acid or its alkyl ester by treating the monomer containing the carbonyl impurities with a trialkyl phosphite or a triaryl phosphite.
