  • Publication number: 20090253819
    Abstract: The invention relates to a process for the preparation of polyurethanes by reacting polyisocyanates a) with compounds having at least two hydrogen atoms reactive with isocyanate groups b), wherein a polyisocyanate a) used is at least one polyisocyanate ai) having an average functionality of greater than 2, a content of diisocyanates of not more than 2% by weight and a content of uretonimines of not more than 4% by weight, based in each case on the weight of the polyisocyanate ai).

  • Publication number: 20070060731
    Abstract: The invention relates to a process for preparing prepolymers containing isocyanate groups by reacting a) diisocyanates with b) compounds having at least two hydrogen atoms which are reactive toward isocyanate groups in the presence of c) catalysts, and subsequently separating off the excess monomeric diisocyanates, wherein the diisocyanates a) used are unsymmetrical diisocyanates and the catalysts c) used are organometallic catalysts and these organometallic catalysts are removed, blocked or deactivated before the monomeric diisocyanates are separated off.
