Abstract: The invention relates to a thermoformed soft foam, made from polyurethane, obtained by reaction of polyisocyanates with polymeric polyols to give a polyurethane soft foam with subsequent irreversible thermoforming of the soft foam obtained thus, at temperatures above the glass temperature of the thermoplastic polymers and the use of polymeric polyols to produce a polyurethane soft foam which may be irreversibly formed in moulds at temperatures of 120 DEG C to 250 DEG C.

Abstract: According to the inventive method, the polyurethane foams are produced by reacting isocyanates with compounds that react with isocyanates in the presence of foaming agents and optionally, catalysts, additives and/or auxiliary agents. The method is characterised in that the reaction is carried out in the presence of at least one of the following compounds (i): alpha , beta -unsaturated carboxylic acid, alpha , beta -unsaturated carboxylic acid derivative, alpha , beta -unsaturated ketone and or alpha , beta -unsaturated aldehyde.

Abstract: Production of polyether polyols comprises use of a multi-metal cyanide complex catalyst in a tall cylindrical reactor having a downward facing spray nozzle in the upper reactor portion, through which the educts and reaction mixture are fed and an outlet, preferably in the lower portion of the reactor to recirculate the reaction mixture via an external circuit and equalizing reservoir. A process for the production of polyether polyols (I) by reaction of diols or polyols with ethylene oxide, propylene oxide and/or butylene oxide in the presence of a multi-metal cyanide complex catalyst (II) comprises carrying out the reaction in a tall cylindrical reactor having a downward facing spray nozzle in the upper reactor portion, through which the educts and reaction mixture are fed, and an outlet, preferably in the lower portion of the reactor, through which the reaction mixture is fed by means of a pump through an external circuit via an equalizing reservoir to the spray nozzle. The external circuit comprises a concentric pipe stretching the entire length of the reactor excluding the reactor ends and contains a heat exchanger integrated within the annulus.
