摘要：
PURPOSE:To obtain a modified isocyanate compound having excellent low- temperature storage stability and useful as a production raw material for polyurethane foam, by reacting an isocyanate with a compound having only one active hydrogen in the molecule. CONSTITUTION:The objective compound can be produced by modifying an isocyanate with a compound having only one active hydrogen in the molecule (e.g. monoalcohol, monocarboxylic acid, etc.) by conventional method. The isocyanate used in the above process is diphenylmethane diisocyanate or a crude diphenylmethane diisocyanate containing >=50% diphenylmethane diisocyanate. The amount of active hydrogen compound added to the reaction system is 0.010-0.350 equivalent of active hydrogen per 1 equivalent of isocyanate group.
