MODIFIED ISOCYANATE COMPOSITIONS AND METHODS OF PREPARING THE SAME

Modified isocyanate compositions having improved properties are provided. The compositions may be formed from the reaction of a isocyanate component, which is a compound terminated with at least one isocyanate group, and an organic acid derivative having the formula (RO)n(M)(E)(EH)3-n, wherein M is nitrogen, phosphorus, arsenic, antimony, or bismuth, n is 1 or 2, each E is independently oxygen, sulfur, selenium, or tellurium, each R is independently hydrogen, an alkyl group, a cyclic aryl group, an acyclic aryl group, a halogen-substituted alkyl group, a halogen-substituted cyclic aryl group or a halogen-substituted acyclic aryl group and wherein the ratio of the weight of the isocyanate component to the combined weight of the organic acid derivative and the isocyanate component is from 0.7 to 0.95. The compositions can be utilized in a variety of applications and are adapted to prolonged storage and transportation. Methods of preparing such compositions are also provided.
