Abstract: An assembly for the containment and dispensing of a beverage includes a portable container fabricated from a pressure deformable, synthetic polymeric resin. An integrally molded projection of the container wall is used to mount one or more drinking vessels such as cups. A single chamber is defined by the container wall, including the projection and functions to contain the beverage to be dispensed. The structure of the container is highly compact, with minimal interior space not utilizable by beverage containment. This avoids an imbalance of the container when it is carried from place to place.

Abstract: A low gloss thermoplastic with good physical properties comprises a blend of a polycarbonate with an acrylonitrile-styrene-acrylate interpolymer and a gloss-reducing amount of a glycidyl (meth)acrylate copolymer.

The label wraps around a portion of the tray providing a display or shelving surface and also covers an adhesive strip on the back of the tray which serves to affix it to a surface upon removal of the label.

Abstract: A process which comprises(a) contacting an excess of a phenol with a ketone in the presence of an acidic ion exchange resin catalyst;(b) recovering thereafter a stream from the acidic ion exchange resin catalyst including the dihydric phenol, unreacted phenol, isomers of the desired dihydric phenol and acid impurities derived from the acidic ion exchange resin catalyst;(c) removing a major portion of the desired dihydric phenol from the stream of (b);(d) separating the stream including phenol, a small portion of the desired dihydric phenol, isomers of the desired dihydric phenol, and acidic impurities derived from the acidic ion exchange resin catalyst into a major stream and a minor stream by volume;(e) introducing into the minor stream created at step (d) sufficient quantities of a tetraorganoammonium borohydride to effectively neutralize the acidic impurities derived from the acidic ion exchange resin catalyst; and(f) recovering from the minor stream desirable dihydric phenol.

Abstract: A process which comprises(a) contacting an excess of a phenol with a ketone in the presence of an acidic ion exchange resin catalyst;(b) recovering thereafter a stream from an acidic ion exchange resin catalyst, said stream including the dihydric phenol, unreacted phenol, isomers of the desired dihydric phenol and acid impurities derived from the acidic ion exchange resin catalyst;(c) removing a major portion of the desired dihydric phenol from the stream of (b);(d) adding to the dihydric phenol effective quantities of a Group II-a metal or transition metal of oxidation number +2 carbonate to color stablize the dihydric phenol;(e) recovering the solid dihydric phenol and the metal carbonate.

Abstract: A multilayer composite which comprises a layer of an ethylene vinylalcohol polymer tied to a thermoplastic polymer with a hydrogenated alkadiene vinyl aromatic block copolymer which is graft modified with an unsaturated acid anhydride or unsaturated dicarboxylic acid thereof.

Abstract: A low-gloss thermoplastic blend contains an aromatic carbonate polymer, strength-improving additivies such as an elastomeric block copolymer and a core-shell acrylic polymer, and a gloss-reducing glycidyl (meth)acrylate polymer.

Abstract: Apparatus for the impregnation of a continuous length of multifilament or multifiber yarns with a molten thermoplastic polymeric resin includes a pair of convex/concave (mating) surfaces for spreading the multifilaments or multifibers apart during their immersion in a bath of the molten resin. The shape, configuration and location of the surfaces facilitates homogeneous impregnation, particularly with highly viscous metls, to produce a uniform and thorough encapsulation of the filaments or fibers.

Abstract: The invention relates to a method of preparing aromatic polycarbonate according to the two-phase interface process. The molecular weight is controlled by the addition of a chain stopper. The use of a phenolic chloroformate as a chain stopper leads to a polycarbonate having a low content of volatile constituents.
