The present invention relates to a process for the production of molded articles via the reaction injection molding technique. According to the RIM process, a reaction mixture is introduced into a closed mold, allowed to react fully, and removed from the mold. More specifically, these reaction mixtures comprise an isocyanate-reactive material, a chain extender, and a stable, liquid diallophanate modified diphenylmethane diisocyanate (MDI). Two specific processes for the preparation of the suitable diallophanate modified diisocyanate are disclosed. These diallophanate modified isocyanates either have an isocyanate group content from about 12 to 30%, or from about 5 to 29%.
