Procedure

The organic polyisocyanate H (NCO content=28.1%) in the form of a prepolymer was prepared in a manner similar to that in the preparation of the organic polyisocyanate B, except that 16.0 parts of an isocyanate-modifying polyether polyol (functionality of the starting material=3; hydroxyl equivalent=1700; and EO content=95%) was reacted with polymethylene polyphenylisocyanate, which isocyanate-modifying polyether polyol was obtained by addition polymerization of propylene oxide and ethylene oxide as alkylene oxide to glycerin as a starting material. The thus obtained organic polyisocyanate H was deposited after it was left at the room temperature for two hours, so that this organic polyisocyanate H could not be used for forming the soft polyurethane foam described below.
