Abstract

There is disclosed a process for controlling the deposition of pitch in a pulping or paper making process, wherein there is incorporated into the composition comprising paper making fibres up to 1.0% by weight, based on the weight of dry fibres in the composition, of a cationic polyelectrolyte which is a poly(diallyl di(hydrogen or lower alkyl) ammonium salt) having a number average molecular weight greater than 500,000.
