摘要： A method produces a uretonimine-modified isocyanate composition having increased low-temperature tolerance. The method comprises providing a polyisocyanate composition comprising 4,4′-diphenylmethane diisocyanate (MDI) and reacting the polyisocyanate composition at a temperature of from about 90° C. to about 115° C. in the presence of a catalyst, and optionally a co-catalyst, such that the isocyanate groups react to form uretonimine oligomers. The reaction of the polyisocyanate composition is quenched with a quenching agent to produce an intermediate composition having an intermediate isocyanate value from about 25.5 to about 28.5. A second polyisocyanate composition is added to the intermediate composition in an amount sufficient to produce the uretonimine-modified isocyanate composition having a final isocyanate value of from about 29.0 to about 29.5.

摘要： A method produces a uretonimine-modified isocyanate composition having increased low-temperature tolerance. The method comprises providing a first polyisocyanate composition having two or more isocyanate groups and comprising 4,4′-diphenylmethane diisocyanate (MDI) and reacting the first polyisocyanate composition at a temperature of from about 90° C. to about 115° C. and in the presence of a catalyst such that the isocyanate groups form carbodiimides for forming uretonimine and uretonimine oligomers. The reaction of the first polyisocyanate composition is quenched with a quenching agent to produce an intermediate composition having an intermediate isocyanate value of from about 21.0 to about 26.0. The intermediate composition is blended with a second isocyanate composition to form a stable uretonimine-modified isocyanate composition.

摘要： A prepolymer system has a monomeric isocyanate content of no greater than about 10% by weight based on 100 parts by weight of the prepolymer system. The prepolymer system comprises a diluent component and a prepolymer component different than and separate from the diluent component. The diluent component has an excess of isocyanate (NCO) functional groups, and comprises the reaction product of a monohydric isocyanate-reactive component and an excess of a first isocyanate component. The first isocyanate component comprises monomeric isocyanates reactive with the monohydric isocyanate-reactive component. The prepolymer component also has an excess of NCO functional groups, and comprises the reaction product of a polyol component and an excess of a second isocyanate component. The prepolymer system can be used to prepare foams via reaction with water. The foams have low density and have excellent adhesion and sound dampening properties for use in cavities of automobile bodies.
