| titleOfInvention | Process for the production of molded polyurethane bodies |
| abstract | The present invention is directed to a process for the preparation of molded polyurethane articles having densities of about 0.8 to 1.4 g/cm3 and a flex moduli according to DIN 53,457 of at least about 1800 N/mm2 by reacting according to the technique of reaction injection molding a) di- and/or polyisocyanates of the diphenylmethane series with b) polyether polyols in the molecular weight range of 500 to 999, c) organic polyhydroxyl compounds in the molecular weight range of 62 to 499 and optionally d) polyethers in the molecular weight range of 1000 to about 10,000 containing at least two isocyanate reactive groups and/or e) aromatic diamines with a molecular weight of less than 500 in the presence of f) catalysts which accelerate the isocyanate addition reaction wherein (i) the polyether polyols used as component b) have at least about 30% by weight of ethylene oxide units incorporated in polyether chains, (ii) component d) is used in a quantity of 0 to about 40% by weight, based on the weight of components b) to e), and (iii) the nature and quantitative proportions of components b) to e) are chosen so that the average hydroxyl number of the mixture of these components is greater than about 300. |
