Process for producing uretidione dimers of isocyanates using catalysts which are bound to inorganic matrices |
| abstract |
This invention relates to a process for preparing a dimer by the steps of: (a) cyclodimerizing a polyisocyanate in the presence of a dimerization catalyst which is covalently bound to an insoluble inorganic matrix by contacting said polyisocyanate with said catalyst at a temperature of between about 20 and about 135° C. in a reaction to form an uretidione-containing cyclodimerized isocyanate wherein a portion of the isocyanate moieties comprising said polyisocyanate are converted to uretidione groups, and (b) separating said catalyst from said cyclodimerized isocyanate in order to stop said reaction after a desired amount of isocyanate moieties in said polyisocyanate have been converted to uretidione moieties. |
