Hair spray compositions containing a carboxylated polyurethane resin, and having a low volatile organic content, are disclosed. The compositions have a low viscosity, and can be applied as a pump spray or as an aerosol, to hold the hair and impart excellent hair set retention properties. The hair spray compositions can be used with a curling iron or a blow dryer to style the hair.

Method of styling hair with hair spray compositions containing carboxylated polyurethane resins

The present invention relates to functionalizable and crosslinkable polyurethanes formed of a polyurethane intermediate including one or more ester groups which react with an amine equivalent to form an amide unit. The polyurethane intermediate comprises the reaction product of alkyl ester of dihydroxypolyacid or dimethylolalkanoic acid, a polyoxyalkylene diol and an organic diisocyanate. The polyurethane is reacted with a solution of an amine equivalent and a solvent or an amine. An article of manufacture can be formed from the polyurethane.

Functionalized polyurethanes

An improved polyurethane is prepared by reacting a diol, an organic diisocyanate and a carboxylic acid with a critical selection of the amount of water in the reaction mixture. The polyurethane has improved adhesion, hydrophilicty and strength. The polymer has improved feel, and washability. Solutions of the polymer have low viscosity in aqueous solutions.

Hair spray compositions containing carboxylated polyurethane resins

An improved amphiphilic diol is prepared with a controlled type and amount of alkylene glycol, catalyst, hydrophobic and hydrophilic diol with diisocyanate and water. Critical selection of the type, molecular weight and ratios of hydrophilic to hydrophobic diol, isocyanate to hydroxyl groups, average molecular weight of the diol component, the amount of water in the reaction mixture produces a polyuretheane having high slip, Shore A Hardness values, wet tensile strength and tear strength. This invention also includes uses of the polyurethane in catheters, shaving products, synthetic valves, veins and arteries, stents, ports, shunts and coatings. Preferably, the polyurethane is used in combination with a filler for application to rubber gloves. In addition, dispersions, lotions, gels and solutions can be formed of the polyurethane.

Hydrophicic and hydrophobic polyether polyurethanes and uses therefor

An improved polyurethane is prepared by reacting a diol component and an organic diisocyanate with critical selection of the amount of water in the reaction mixture and the diol component. The diol component is a long chain polyoxyethylene glycol optionally mixed with a low molecular weight polyoxyethylene glycol. A tough gel can be formed by mixing the polyurethane in a diol or triol and water solution. The tough gel can be used in burn and wound dressings, electroconductive pads, high slip materials and surgical implants. An optically clear gel can also be formed. Solutions and emulsions can be formed of the polymer and can be combined with fillers to form face creams and antiperspirants. A film can cover one side of the gel for burn and wound applications. The gel can be used in squeeze tubes and in spray cans in burn wound care dressings and industrial applications and in bags and containers for use in plastic surgery implants.

A paper like butene-1 polymer sheet material is made by extruding a composition comprising (a) about 20 to 97% by weight of a butene-1 polymer having a molecular weight in excess of about 20,000, an isotacticity of at least about 25% and a butene-1 content of at least about 50% by weight, and (b) about 3 to 80% by weight of at least one normally solid filler insoluble in said polymer, to form a sheet, and stretching said sheet at least about 5% beyond its yield strain. The filler may be organic or inorganic and the sheet is preferably stretched at least about 20% beyond its yield point. The sheet is characterized by a novel surface appearance when scanned in an electron microscope, by dimensional stability and by approximately equal strengths in all directions as evidenced by a maximum tensile strength ratio of about 13:1 in mutually perpendicular directions.

Paper-like butene-1 polymer compositions

A golf ball is formed by molding a center of a homogeneous mass of polybutadiene with a metal salt of an unsaturated acid such as zinc dimethacrylate and a filler such as zinc oxide, and a cover of an ionic copolymer is formed about the center by coating as by electrodeposition or by molding. Molding of the center can successfully be carried out quickly above 170.degree. C. and the balls can be driven long distances. The centers can be molded with projections which are used for proper centering when molding a cover thereabout.
