摘要：
Compositions which will rapidly set to produce solid, rigid polyurethanes without the use of a catalyst comprise an amine initiated polyether polyol such as triethanol amine, an organic aromatic polyisocyanate, such as toluene diisocyanate and a liquid modifier compound having a boiling point above about 150.degree. C such as a cyclic sulfone.
