    • Disclosed are novel compositions capable of catalytically trimerizing organic isocyanates said compositions comprising solutions of the reaction products obtained by reacting in an inert solvent in substantially equimolar proportions electron-rich ketene-aminals with electron-poor olefins having the respective formulae (I) and (II) ##STR1## The variously substituted electron-rich ketene-aminals (I), as the name implies, have high electron density associated with the double bond because of the two tertiary amine groups while the electron-poor olefins (II) have the opposite situation due to the presence of electron withdrawing substituents R.sub.9 and R.sub.10.Also discosed is an improved process for trimerizing organic isocyanates using the above catalyst compositions including the preparation of polyisocyanurate polymers and isocyanurate-modified polyisocyanates.

    • Disclosed is a novel class of amidinium salts having the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 when taken individually are independently selected from lower-alkyl, aralkyl and cycloalkyl, and, when taken together with the respective nitrogen atoms to which they are attached, R.sub.1 together with R.sub.2, and R.sub.3 together with R.sub.4 independently represent heterocyclic groups having 5 to 7 ring atoms, R.sub.5, R.sub.6, R.sub.7, and R.sub.8 are independently selected from hydrogen, lower-alkyl, aryl, aralkyl, and cycloalkyl.The amidinium salts are very active catalysts for converting organic isocyanates to products containing isocyanurate and carbodiimide linkages.
    • 公开了一类新的具有下式的脒鎓盐:其中R 1,R 2,R 3和R 4分别独立地选自低级烷基,芳烷基和环烷基,并且当与各自的氮原子一起 R 1和R 2一起连接,R 3与R 4一起独立地表示具有5至7个环原子的杂环基,R 5,R 6,R 7和R 8独立地选自氢,低级烷基,芳基,芳烷基和环烷基。 脒鎓盐是将有机异氰酸酯转化为含有异氰脲酸酯和碳二亚胺键的产物的非常活泼的催化剂。
