  • Patent number: 4891436
    Abstract: A process for the manufacture of bis-methylene spiro-orthocarbonate (BMSOC) wherein methyallyl chloride is subjected to the action of chlorine gas to form a mixture of 1,1-dichloromethyl ethylene and other chlorinated hydrocarbons which need not be and are not separated. The mixture is merely treated wich an alkali metal acetate such as sodium acetate to yield an easily separable second mixture by fractional distillation. The desired 1,1-diacetoxymethyl ethylene is thus recovered in high yield. It is then converted by transesterification in over 90% yield to the bismethylene spiroorthocarbonate (BMSOC). BMSOC is useful as a component for coatings composites, adhesive formulations and the like, which have the unique ability to (a) cure by free radical initiation and (b) expand during cure. BMSOC may be used as a component for dental composites, i.e. filling materials, because it reduces the possibility of leakage at the margin, i.e. at the composite-enamel interface and as a component in bone cements.

  • 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.
