Abstract: ABSTRACT OF THE DISCLOSURE           A light stable polyurethane elastomer is prepared in the absence of solvent from a polyol, a chain extender and an aliphatic polyisocyanate using a thio tin organic compound, containing sulfur directly attached to the tin, as a heat activated catalyst.  E.g., a solventless liquid composition comprising an hydroxy-terminated polyester, a chain extender, and hydrogenated MDI, containing dibutyl-tin S,S-bis(isooctyl mercaptoacetate) as a catalyst, has a pot life in excess of 25 minutes at room temperature but upon heating 1 minute at 375°F. gels to a solid state.  Because of this combination of long pot life and rapid cure, the composition is suitable for such applica-tions as making coated fabrics and films. and in other liquid processing techniques, e.g., rotational casting, liquid injection molding, and the like.

Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus for focussing and declustering trace ions travelling from a gas through an orifice into a vacuum chamber and to a mass analzyer in the vacuum chamber.   Advantage is taken of the free jet expansion of the gas into the vacuum chamber by applying an electric focussing field in a specific region of the free jet.  The region is selected sufficiently close to the orifice that the gas density limits the kinetic energy spread which the ions can acquire under the applied field, typically to 2 ev or less, while the early focussing increases the available ion signal. Declustering can be collision induced in the region by providing a field in the region sufficient to impart an internal energy of between 0.1 and 1.5 ev to ions in the region. The kinetic energy which the ions can acquire under the applied field is still limited by the density of the gas in the free jet, so that the kinetic energy spread which the ions can acquire is still limited. Preferably the focussing and declustering fields are produced by a single conical tapered lens element located at distance X? from the orifice, where    and D is the orifice diameter, for atmospheric pressure and room temperature source conditions.          The electric field between the lens element and the mass spectrometer is then controlled to limit the energy spread imparted to the ions in their travel from the lens element to the mass spectrometer.
