Abstract: Polymers of a polymerizable mixture comprising an ethylenically unsaturated acid and an oligomer of an allyl-containing ester of acrylic acid or methacrylic acid are useful as thickening and bodying agents when partially or completely neutralized.

Abstract: Apparatus for use in hospitals and the like for administering to a patient medicated liquid solutions, or blood. The improvement comprises an improved control valve for regulating and filtering the fluid flow of said solutions into the body. The liquid control valve is of a vernier control type with a selective adjustment to the prescribed rate of fluid flow with limit stops for positive shut-off, and full by-pass. The valve is positioned on the patient adjacent the point of entry of the fluid into the body. The apparatus -- adaptable to the commercial infusion administration single use disposable kits -- comprises a tapered fluid control spool, having a series of longitudinal grooves. With the spool resiliently snapped into and positioned in a housing the grooves are graduated openings that traverse the fluid supply port. The length, depth, shape and spacing of the grooves together with geometric shape of the supply port provides a variable resistance to the fluid flow to provide an exact program of flow.

Abstract: Novel polyacrylic hot melt adhesives prepared by blending a polymer having a Tg of -85.degree. to 0.degree. C. with a polymer having a Tg of 20.degree. to 150.degree. C. are disclosed.

Abstract: Compositions comprising an oxazolidine and a polyanhydride cure in the presence of moisture to afford polymeric materials. The compositions can be used in forming caulks, films, fibers, paints, seamless flooring, coatings, impregnants and adhesives for both natural and synthetic materials.

Abstract: Polymeric materials which comprise a hydroxyalkyl ester of acrylic acid or methacrylic acid, a monoethylenically .alpha.,.beta.-unsaturated carboxylic acid, and an alkyl ester or esters of acrylic and/or methacrylic acid are partially neutralized, isolated, and powdered to give useful powder coating compositions. The composition may be utilized for coating metallic articles.

Abstract: Polymeric materials are disclosed which comprise a hydroxyalkyl ester of acrylic acid or methacrylic acid, a monoethylenically .alpha.,.beta.-unsaturated carboxylic acid, and an alkyl ester or esters of acrylic and/or methacrylic acid are partially neutralized, isolated, and powdered to give useful powder coating compositions.The compositions are particularly adapted to provide coatings on metals, a method for accomplishing this being disclosed.

Abstract: Polymeric materials which comprise a hydroxyalkyl ester of acrylic acid or methacrylic acid, a monoethylenically .alpha.,.beta.-unsaturated carboxylic acid, and an alkyl ester or esters of acrylic and/or methacrylic acid are partially-neutralized, isolated, and powdered to give useful powder coating compositions.

Abstract: The invention provides new copolymers of (I) monounsaturated or diunsaturated addition polymerizable polyester monomers and (II) vinyl monomers. The resulting copolymer is considered to be a vinyl polymer (e.g., an acrylic polymer) containing a pendant polyester plasticizer as an integral part of the polymer. It is not essential that the copolymer be crosslinked or thermoset, and yet the plasticizer is a permanent part of the polymer--not subject to being leached out of the polymer, as is the case with an external plasticizer. While thermosetting or crosslinked compositions are known which bind external plasticizers to the substrate, the very object of attaining flexibility is to a large extent defeated by the binding agent itself when present in large amounts. Also provided are new monomers in the form of unsaturated polyesters having one or two double bonds per molecule.

Abstract: Apparatus for use in hospitals and the like for administering to a patient medicated liquid. The improvement comprises a control for regulating and visually indicating the rate of fluid flow into the body. The system is equally applicable to intravenous, intrarterial, or subcutaneous. A positive action liquid control valve together with a flow meter is positioned on the patient adjacent the point of entry of the fluid into the body. The apparatus -- adaptable to the commercial single use disposeable kits -- in its preferred embodiment, is strapped to the wrist of the patient. The apparatus is further adapted to receive the conventional injection needle for the addition of other medication.
