Abstract: Solutions of triorganotin lithium are described having low residual concentrations (preferably less than 2,000 ppm) of halide. These are produced by a two-step process.Triorganotin halide is reacted with lithium to produce hexaorgano ditin and a precipitate of lithium halide. The lithium halide precipitate is removed by filtration and/or use of highly concentrated reaction conditions. Then the hexaorgano ditin is further reacted with lithium to form the triorgano substituted tin lithium. The lithium halide is less soluble in hot tetrahydrofuran (THF) and/or more concentrated solutions. THF is a preferred solvent for the reaction. The low-temperature reactions described result in low amounts of inactive and/or undesirable byproducts. These triorganotin lithium compounds are useful as anionic initiators that result in polymers with terminal tin compounds, e.g., triorganotin, attached to the terminal end of the polymer where initiation occurred.

Abstract: A fire resistant and impact resistant transparent laminate comprising at least two spaced parallel sheets of transparent material selected from the group consisting of ceramic glass and polymeric material, at least one optically transparent fluorocarbon polymer modified with polar groups, at least one optically transparent glass or resinous inner layer between said parallel sheets, and at least one layer of an optically transparent intumescent gel on at least one side of said inner layer.

Abstract: A heat sealable, adhesive-free seam and closure fabrics and clothing comprising the combination of a fabric scrim and a heat sealable water and vapor resistant coextruded laminations which provides a barrier against liquid substances and vapors. The coextrusion laminations are in abutment or overlap and comprise a film layer with an outer and inner layer of low density polyethylene and an intermediate layer of a copolymer of ethylene and vinyl alcohol. The laminations are fusion bonded to a portion of the scrim in a manner whereby the polyethylene flows from said lamination, encapsulates the ends of the intermediate layer of the laminate and forms weld points with the said scrim to prevent penetration by liquid substances and vapors.

Abstract: An improvement in ventilating protective garments used against chemical agents. There is provided an arrangement of the air supply and the air exhaust so that the air cools the occupant and sweeps across the visor of a headpiece to prevent fogging. A regulator is used to maintain a degree of inflation in the garment by the incoming air.

Abstract: A fire and chemical resistant fabric having anti-static properties which comprises at least one laminate formed by coextruding a pair of polymeric sheets with an intermediate layer of a polar resin or hydrophilic polymer which is adhered to a fabric scrim comprising a blend of polyester and cellulosic fibers, the fabric scrim containing an effective amount of an anti-static and fire resistant agent.
