    摘要： This invention relates to a process for the production of polyurethane foams in closed molds using mixtures of organic polyisocyanates with certain compounds which liberate carbon dioxide under the catalytic influence of basic compounds. In this process a mixture of polyisocyanates and compounds which liberate carbon dioxide under the catalytic influence of basic compounds is reacted with organic compounds containing hydrogen atoms which are reactive with isocyanate groups, which organic compounds are mixed with basic compounds and/or have basic compounds chemically built into them. The process is suitable for the production of any polyurethane foams in a closed mold, but is preferably applied to the production of semi-hard and particularly of hard polyurethane foams having a dense outer skin.

    摘要： A process for preparing modified polyisocyanates in which an organic polyisocyanate is reacted with a polyamine present in less than stoichiometric amount. Polyamines suitable to this process include (a) polyamines having more than three nonaromatically bound, basic nitrogen atoms of which at least two are primary and/or secondary amino nitrogen atoms, and (b) polyamine mixtures having an average of more than three nonaromatically bound, basic nitrogen atoms of which at least two are primary and/or secondary amino nitrogen atoms. These modified polyisocyanates are particularly useful starting materials for production of polyurethane plastics by the isocyanate-polyaddition process.

    摘要： A process is described for the successive production of at least two non-cellular molded articles differing in their mechanical properties. Both articles are based on organic polyisocyanates which are trimerized in the presence of compounds which are reactive with isocyanate groups where the equivalent ratio of NCO groups to groups reactive with NCO groups is varied within the range of 1:0.8 to 1:0. In a second embodiment, a uniform article is produced having anisotropic mechanical characteristics varying continuously and/or stepwise.
