Abstract: Iron contaminants are associated with a beta-dicarbonyl in an isocyanate composition that includes polymeric methylene diphenyl diisocyanate (PMDI). The association of the iron contaminant and the beta-dicarbonyl is thought to minimize a catalytic effect of the iron contaminant when the isocyanate composition is reacted with a polyol to form a polyurethane. The iron contaminant is associated with the beta-dicarbonyl in a method that includes the step of providing the isocyanate composition and the step of combining the beta-dicarbonyl and the isocyanate composition. The isocyanate composition is included in a polyurethane system and typically includes the association product of the iron contaminant METHOD and the beta-dicarbonyl.

Abstract: 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.
