FOAMED POLYURETHANE, SYNTHESIS METHOD THEREOF AND CONTINUOUS METHOD FOR SYNTHESIS OF ALKOXYLATED HYDROXYLATE OF PLANT OIL Russian patent published in 2011 - IPC C08G18/10 C08G65/10 C08G65/26 C08G18/48 C08G18/66 C08G101/00 

FIELD: chemistry.

SUBSTANCE: invention relates to foamed polyurethane used in a wide range of articles, such as inner component parts of cars, structural polyurethane foam, floor covering and sports race tracks, as well as a production method thereof and a continuous method of producing alkoxylated hydroxylate of plant oil. The foamed polyurethane is a product of reaction of at least one polyisocyanate and at least one alkoxylated hydroxylate of plant oil containing from approximately 15 wt % to approximately 90 wt % alkoxylate relative the weight of the alkoxylated hydroxylate of plant oil, wherein alkoxylation is carried out in the presence of a catalyst based on a double metal cyanide (DMC) in amount of 0.0005-1 wt % relative the amount of a polyol derivative, optionally at least one polyol which is not based on plant oil, in the presence of at least one foaming agent and one catalyst different from the catalyst based on DMC, selected from a group comprising organotin and/or amine catalysts, optionally in the presence of at least one surfactant, pigments, fire retardants and filler materials.

EFFECT: foamed polyurethane produced using environmentally acceptable, renewable components, in particular alkoxylated hydroxylate of plant oil, which enables use of the foamed polyurethane in fields where there are high environmental requirements and/or high hydrophobic properties.
