Abstract

The use as a foam suppressant in alkaline or neutral paper making employing calcium carbonate as filler of a water soluble salt of a polybasic acid improves paper machine utilisation and reduces the formation of white pitches in the paper particularly when the paper is sized with an alkyl or alkenyl succinic acid anhydride and other reactive sizing compounds.
