    摘要: The invention describes an improved process for preparing polyols by reacting a mono-epoxy compound such as propylene oxide with a hydroxyl-containing initiator compound such as glycerine in the presence of a catalyst, the improvement being that the catalyst is added in the form of a calcium, strontium or barium salt of an organic acid such as acetic acid.Polyols prepared by this process can be employed to prepare polyurethanes without removing the catalyst.

    摘要: Rapid-setting polyurethanes are prepared from organic aromatic polyisocyanates and polyols having an average functionality of 2-8 and an equivalent weight less than 500 by admixture thereof in the presence of a non-amine nitrogen-containing compound such as urea as a catalyst therefor.
