Abstract

1383184 Polyisocyanates containing sulphonic acid and/or sulphonate groups BAYER AG 1 June 1973 [3 June 1972] 26221/73 Heading C2C Liquid aromatic polyisocyanates which contain sulphonic acid and/or sulphonate groups are prepared by reacting a liquid multicomponent mixture of aromatic polyisocyanates with sulphur trioxide, oleum, sulphuric acid or chlorosulphonic acid and optionally completely or partly neutralizing the sulphonation product with a basic compound.
