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

Production of polyurethane foams in the presence of aminoalkylor aminophenylimidazoles as catalyst, and the use of these catalysts for the preparation of polyisocyanate polyaddition products 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 ag ents, in the presence of d) blowing agents, e) catalysts from the group consisting of aminoalkyl- and amino phenylimidazoles of the formula <IMG> (I) and/or <IMG> (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.
