| titleOfInvention | Polyisocyanate compositions for the preparation of flexible polyurethane foams |
| abstract | A liquid polyisocyanate prepolymer composition comprises the reaction product of about 50.0 to 90.0 percent by weight of an isocyanate blend (a.) having 55.0 to 75.0 weight percent 4,4'-diphenylmethane diisocyanate (MDI), 17.0 to 27.0 weight percent 2,4'-MDI, 1.0 to 10.0 weight percent 3-ring MDI oligomer, and 1.0 to 15.0 weight percent n-ring MDI oligomer (n greater than 3); about 5.0 to 30.0 weight percent of a polyhydroxy containing polyol (b.) having a molecular weight of from 700 to about 6,000; and about 15.0 to 75.0 weight percent of toluene diisocyanate (c.). The resulting isocyanate prepolymer composition has a free NCO content of from about 30.0 to 45.0 weight percent and particularly desirable flow characteristics. The isocyanate prepolymer composition can be used for making a polyurethane foam. |
