    摘要: A system for use in making molded polyurethane objects by an open or closed casting process, said system comprising

    (A) an aromatic polyisocyanate; and
    (B) an active hydrogen-containing composi­tion comprising

    (i) a polyhydric alcohol having an average molecular weight in the range of about 1000 to about 8000 and an average functionality of about 2 to about 4;
    (ii) a polyhydric alcohol having 2 to 12 carbon atoms and an average functionality of about 2 to about 3; and
    (iii) a secondary monoamine of the formula
          R-NH-Rʹ
    wherein R and Rʹ are independently saturated aliphatic groups having 1 to 20 carbon atoms, provided that said secondary monoamine contains at least 4 carbon atoms.
