Abstract: Disclosed is a process for preparing polymeric compositions which are suitable for coating medicaments or for use in cosmetic formulations and the novel compositions prepared therefrom. The process makes stable, colloidal, latex-like dispersions of coating polymers which can be readily dried to form polymeric powder materials. The process makes use of a novel combination of a water-in-oil emulsifier and an oil-in-water emulsifier.

Abstract: The present invention is directed to a hot-melt adhesive containing at least one propylene/1-hexane copolymer. The adhesive contains an amount of a low viscosity, substantially crystalline wax, having a melting point of about 90.degree. C. to about 125.degree. C., sufficient to improve the elastic delamination resistance of the adhesive. The adhesive are particularly useful in disposable diaper construction.

Abstract: A lignin-modified phenol-formaldehyde resin for use as an adhesive for particulate wood products is disclosed which is prepared by reacting phenol and formaldehyde with an aqueous alkaline solution of an organosolv lignin. The organosolv lignin used in the formation of the resin is obtained from a pulping liquor prepared from particulate wood material from hardwood trees, aqueous polar organic solvent, and an acid catalyst. The resin allows for replacement of phenol or organosolv lignin at a level of up to 40% without detrimentally affecting its performance in terms of bonding strength or durability. The resin of the present invention is also superior to prior art lignin-modified resins in that it is low in sulfate, ash and sulfur residues, and thus will not give off distracting or harmful sulfur odors during resin preparation or hot-pressing of the adhesive and is unaffected and not solubilized by water.

Abstract: This invention concerns blends of poly(ethylene terephthalate), poly(ethylene naphthalate) and a compatibilizing amount of a copolyester which comprises (1) an acid component comprising repeating units of from about 10 to about 20 mole % terephthalic acid and about 80 to about 90 mole % naphthalenedicarboxylic acid, and (2) a glycol component comprising repeating units of ethylene glycol. Clear containers containing less than 10% haze produced from such blends are useful for a variety of packaging applications, particularly hot-fill food and beverage containers where good barrier and clarity are needed.
