Abstract: A tertiary amine compound is shown and described herein. The tertiary amine is a reaction product of an isocyanate and a compound bearing an active hydrogen and a bicyclic tertiary amine in its molecule. The tertiary amine compounds have been found to be suitable as catalysts for producing polyurethanes. Also shown and described are processes employing the tertiary amine compounds in a reaction of an isocyanate and an alcohol in the presence of the tertiary amine compounds. Further, also shown and described is a method for making the tertiary amine.

Abstract: The present invention relates to the injection of water and gas, either simultaneously or alternately, into subsea wells in order to enhance production and the oil recovery level. Thus, the present invention provides a subsea system for pressurizing a subsea oil reservoir injecting at least one of water and gas, comprising (i) at least two subsea injection wells (4, 4?), each subsea injection well (4, 4?) being connected to a production unit (5) by means of a single subsea line (1, 2) which is connected to the respective subsea injection well (4, 4?) by a main injection mandrel (6, 6?), and (ii) at least one jumper (3), each jumper (3) hydraulically connecting two of the at least two adjacent subsea injection wells (4, 4?) through annular mandrels (7, 7?). The present invention further provides a subsea reservoir pressurization method associated with the above-described system.

Abstract: The present invention pertains to the co-catalysis of autocatalytic amine-based polyols with acid blocked, gelling, amine catalysts, and to the use of this catalyst combination in the production of low density polyurethane foams having improved aging characteristics and reduced VOC's (Volatile Organic Compounds) emissions.

Abstract: A process for producing a multi-layered article having a soft, leather-like feel comprising first introducing into a suitable mold a first liquid formulation designed to produce the top elastomeric layer on the finished article. A release agent is then applied on the elastomeric layer in the area where it is desired not to have adherence of the elastomer to the foam. Before the elastomeric layer is completely cured, a second liquid foam producing formulation, designed to produce a soft foam, is poured into the open mold. The elastomeric layer of the resulting article is integrally attached to the foam in the areas not containing the release agent.

Abstract: A storage stable or easily redispersible dispersion of melamine, urea or a blend thereof in a polyol, polymer polyol or a blend thereof is produced by the addition of an alkylbenzenesulfonate salt to the dispersion. Foams, polyurethane foams and other polyurethane materials made from storage stable or easily redispersible dispersion of the present invention show improved combustion resistance properties.

Abstract: A process for preparing a dispersion of a filler e.g., melamine, urea or borax in a dispersion or graft polymer polyol is provided. The process comprises (1) dispersing the filler in a suitable basestock (e.g., a polyether polyol) and (2) thereafter using this as the basestock for preparing the dispersion or graft polymer polyol.The polymer which is prepared in dispersed form in the second step may be for example (1) the reaction product of a polyamine, hydrazine or hydrazide and an isocyanate (PHD polymer) or (2) the reaction product of an olamine and an isocyanate (PIPA polymer). Alternatively styrene and acrylonitrile can be graft polymerised in the basestock in step (2). The new dispersion or graft polymer polyols containing dispersed filler are useful in the manufacture of fire resistant polyurethane foam for e.g., furniture applications.
