Production of polyurethane foams in the presence of aminoalkyl- or aminophenylimidazoles as catalyst, and the use of these catalysts for the preparation of polyisocyanate polyaddition products |
摘要 |
The invention relates to a process for the production of (flexible) polyurethane foams having reduced odor and reduced fogging values by reacting a) modified or unmodified organic polyisocyanates with b) relatively high-molecular-weight polyhydroxyl compounds and, if desired, c) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of d) blowing agents, e) catalysts from the group consisting of aminoalkyl- and aminophenylimidazoles of the formula <IMAGE> (I) <IMAGE> (II) and, if desired, f) additives, and to the use of the aminoalkyl- and aminophenylimidazoles of the formula (I) and/or (II) as catalysts for the preparation of polyisocyanate polyaddition products.
