摘要

Provided is a composition for forming polyurethane resin having a balance between reactivity and reducing viscosity and successfully imparting low-temperature storage stability, for use in fixing a hollow or fiat sheet fiber separation membrane; and an MDI prepolymer containing a large amount of allophanate group without a metal compound and a method for producing the same while successfully controlling a reaction. Solution is provided by using a composition for forming polyurethane resin, containing a specific isocyanate group-containing compound; allophanatizing MDI with a tertiary amine catalyst without containing a metal catalyst; and reacting in the presence of at least one selected from the group consisting of a carboxylic acid amide, a sulfonic acid amide and an active methylene compound.
