  • Patent number: 4374945
    Abstract: Certain substituted thioglycolates and thiopropionates were found useful as secondary stabilizers for polymers, particularly polyvinyl chloride, when used in conjunction with metal octanoates, such as zinc octanoate, as the primary stabilizer. The specific thioglycolates and thiopropionates are those formed by thio adducts to the double bond of a monomer, such as the product of reacting isooctyl thioglycolate with glycidyl acrylate, to provide isooctyl S-2(glycidyloxycarbonyl)ethyl thioglycolate, as an example.

  • Patent number: 4262847
    Abstract: A urethane foam gun is disclosed in which polyisocyanate and polyol feed streams are mixed with air under pressure within the gun with vigorous intermixing in the outlet nozzle to a condition ready for application. Once applied the foam polymerizes in place. The gun is formed with an integral block design in which dual plug valves are mounted for control of the streams. Actuation is achieved by a trigger valve mounted on the gun, and a second gun-mounted valve controls a solvent flush for cleaning to avoid polymerization within the gun itself. The gun is useful for foam-in-place applications, such as protective packaging.

  • Patent number: 4166056
    Abstract: A waste stream of non-volatiles is recovered (NVR) as a by-product from the oxidation of cyclohexane to cyclohexanone and chlohexanol in the process for making adipic acid. The NVR is dehydrated, and then reacted with an esterifying polyol to form a polyester polyol which was found to be useful in the dispersion of vinyl resins. Those polyester polyols with low acid numbers of less than 10, and ,referably less than 2, were found to be most effective as vinyl dispersion plasticizers. A particularly useful end-product is a tough vinyl resin film having a Shore A hardness of approximately 55. End-products may also be used in wire coatings and coverings.

  • Patent number: 4160065
    Abstract: A latex suitable for forming improved water-resistant polyurethane products. The latex is prepared in an aqueous system by reacting an NCO-terminated, quaternized, preferably linear, polyurethane prepolymer with water and chain-extending the resulting polyurethane-urea with a difunctional or polyfunctional reagent containing groups reactive with primary amino groups, such as epoxy groups, anhydrides and aldehydes, thus increasing the molecular weight of said polyurethane-urea. The latex thus formed can be dried into highly water-resistant films, coatings, and the like.
