Abstract
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.
