    Abstract: The present invention provides a process, which includes: partially trimerizing isophorone diisocyanate in the presence of a catalyst having the formula: [R—NX3]⊕Y⊖ wherein R and X are butyl groups and Y− is CH3COO−; or wherein R is a benzyl group, Y− is a carboxylate anion having from 4 to 8 carbon atoms and each X is an alkylene group having from 2 to 3 carbon atoms, wherein the three alkylene groups share a common carbon atom and, together with the N atom in the formula, form a tricyclic structure, and wherein at least one alkyene group has at least one OH group in an &agr; or &bgr; &ggr; position relative to the N atom, to obtain a monomer-containing polyisocyanurate mixture. The present invention also provides a monomer-containing polyisocyanurate mixture made from the above process.

    Abstract translation: 本发明提供了一种方法,其包括:在具有下式的催化剂存在下部分三聚异佛尔酮二异氰酸酯:其中R和X是丁基,Y-是CH 3 COO-; 或者R为苄基时,Y-为碳原子数为4〜8的羧酸根阴离子,X为碳原子数2〜3的亚烷基,其中,3个亚烷基具有共同的碳原子, 式中的N原子形成三环结构,并且其中至少一个烷基在相对于N原子的α或βγ位置具有至少一个OH基团,以获得含单体的聚异氰脲酸酯混合物。 本发明还提供由上述方法制备的含单体的聚异氰脲酸酯混合物。
