The present invention is directed to novel metal organocomplexes as catalysts for the reaction of compounds with isocyanate and hydroxy functional groups to form urethane and/or polyurethane and the process employing such catalysts. More particularly, the present invention is directed to catalysts comprising a mixture of tetrakis-(2,4-pentanedionato) zirconium and a compound selected from the group consisting of a diketone:
R1COCH2COR2 (II)
and
R1OCOCH2COR2 (III)
wherein each of R1 and R2 is a branched or linear C1-C20 hydrocarbon and the total number of carbons in R1+R2 is at least 4. These novel catalysts are useful for the production of urethanes and polyurethanes which are important in many industrial applications, such as: coatings, foams, adhesives, sealants, and reaction injection molding (RIM) plastics.
本发明涉及作为催化剂的新型金属有机络合物,用于使具有异氰酸酯和羟基官能团的化合物反应生成聚氨酯和/或聚氨酯,以及采用这种催化剂的工艺。更具体地说,本发明涉及由四-(2,4-戊二酮酸)锆和选自由二酮组成的组的化合物的混合物组成的催化剂:
R1COCH2COR2 (II)
和
r1ococh2cor2 (iii)
这些新型催化剂可用于生产聚氨酯和聚氨酯,它们在许多工业应用中都非常重要,例如:涂料、泡沫、粘合剂、密封剂和反应注塑成型(RIM)塑料。
