| abstract |
The present invention provides flexible polyurethane foams made from at least one polyisocyanate and at least one alkoxylated vegetable oil in the presence of a double metal cyanide catalyst (CMD), optionally at least one non-vegetable oil based polyo1, optionally in the presence of at least one of the expanding agents, surfactants, pigments, flame retardants, catalysts and fillers. Alkoxylated vegetable oils do not harm the environment, they are bioderivative polyols that can be used to increase the "green" content of polyurethane foams, without having detrimental effects on the properties of the foams. |
