摘　　要：综述了异氰酸酯缩合生成碳化二亚胺催化剂的开发现状,包括磷杂环化合物、磷酸酯类化合物、金属有机化合物、聚合物接枝固相催化剂4大类。其中聚合物接枝固相催化剂是新型环保型催化剂,是异氰酸酯合成碳二亚胺类催化剂的发展方向。The Catalyst used for preparation of carbodiimide from condensation of isocyanate were reviewed in this paper, including phosphorus-containing heterocycle compounds, phosphonate,organic metal compounds and polymer-grafting solid catalysts. The polymer-grafting solid catalyst is a new catalyst beneficial to environment and is developmental direction in preparation of carbodiimide from condensation of isocyanate.
