Abstract: Low-fogging catalysts for polyurethane (PU) production, obtained by reacting (a) polymeric compounds containing carboxylic acid and/or anhydride groups with (b) compounds with primary or secondary amino group(s) and/or compounds with tertiary amino group(s) and group(s) which react with acid or anhydride groups. Independent claims are also included for: (i) A process as described above for the production of low-fogging catalysts; (ii) a process for the production of PU by reacting polyisocyanates with compounds containing at least two isocyanate-reactive groups in presence of these catalysts; (iii) polyurethanes obtained by this process.
