PROCESS FOR PRODUCING POLYURETHANES USING BIS-(4- AMINO-2- HALOGENO-3, 5-DIALKYLPHENYL) -METHANE AND ARTICLES PREPARED THEREFROM |
摘要 |
In a process for producing polyurethanes by reacting a) di- and/or polyisocyanate, and b) di- and/or polyhydric alcohol in the presence of at least one metal compound as a catalyst, there is added to the reaction mixture at least one bis-(4-amino-2-halogeno-3,5-dialkylphenyl)-methane of general formula (I): wherein Hal denotes C1 or Br and R1 to R4 are the same or different and each denote an alkyl groupe having 1 to 4 carbon atoms, and at least one metallo-organic compound is used as the catalyst. An article produced therefrom contains bound residues of the foregoing formula.
