An improved process is provided for the formation of cellulose acetate filamentary material and film. Secondary cellulose acetate is dissolved in a solvent at an elevated temperature and elevated pressure to form a homogeneous solution, with the solvent being incapable of dissolving the secondary cellulose acetate at ambient conditions. The cellulose acetate solution is extruded through an appropriate shaped orifice into a gaseous atmosphere provided at substantially atmospheric pressure. A rapid precipitation or phase separation reaction occurs in the gaseous atmosphere wherein the solvent separates from the cellulose acetate to form a solid filamentary material or film which is subsequently collected. The solid product may be dried to remove remaining traces of solvent. The process is capable of implementation at rapid spinning speeds while utilizing relatively short zones wherein the phase separation is accomplished.

There are provided oxygen stable rosin-primary polyhydric alcohol esters and a process for esterifying a rosin with a primary polyhydric alcohol in the presence of catalytic amounts of an arylsulfonic acid added either simultaneously or subsequent to the initial rosin-polyhydric alcohol reaction to complete esterification and to obtain a rosin ester having markedly improved oxidation stability and good color.

A utilitarian and/or decorative object and a method for forming the object fabricated mainly of a plastic material, such as polyester, having a metallic outer face which thereby imparts to this object the appearance and/or hand of a like object made entirely of metal. In this technique, a mixture of a liquid monomer, a curing agent therefor, a dispersion of metal particles and floatable particles are poured into a mold for forming the object. The metal particles are permitted to settle in the mold or the mold is centrifuged to cause the metal particles to migrate toward the outer or lower region of the piece and concentrate in this region before the monomer polymerizes and hardens to bind the particles. At the same time the floatable particles, such as glass or ceramic microspheres, rise to the inner or upper region of the piece and concentrate in this region before the monomer polymerizes and upon hardening of the monomer maintains the article in the desired shape without distortion from warping from uneven shrinkage. After removal from the mold, the outer face of the piece is polished and buffed to remove the fine plastic skin from the surface of the metal particles and to polish the exposed metal surface, whereby the resultant plastic piece simulates the appearance of a solid metal piece.

Enhancement of the coffee flavor of foodstuffs is achieved by the addition of a small but effective amount of a mixture of a) 2-nonenal, and/or 2-nonenol and particular derivatives thereof; and b) a compound represented by ##SPC1## Where X is oxygen or sulfur, R is lower alkyl, and R. sub. 1, R. sub. 2, and R. sub. 3 is hydrogen or alkyl provided at least one of R. sub. 1, R. sub. 2, and R. sub. 3 is alkyl of two to twelve carbons.
