| titleOfInvention | Method for preparing urethane prepolymer comopsitions |
| abstract | A method for producing urethane-based prepolymers, especially for use in polyurethane elastomers, comprises the steps of: (a) providing a monomeric methylene bis(phenylisocyanate) composition having at least about 65.0 weight percent of diphenylmethane 4,4' -diisocyanate based on the total weight of all isomers; and (b) introducing a polyol composition having an average molecular weight of less than about 600 to said methylene bis(phenylisocyanate) composition with mixing; wherein the resulting prepolymer has an average NCO content of between about 20.0 percent to less than about 30.0. The prepolymers provide finished products that exhibit high clarity and high gloss when polished. An added feature of the present invention is that the prepolymers are stable liquids at room temperature. |
