Abstract

Procedure for the treatment of paper pulp, by means of aqueous emulsions of organosilicon polymers, characterized in that organic condensates obtained by reaction of amine polymers are added to these organosilicon polymers at a rate of 5 to 40% of the weight of the organosilicon polymers. that include some formula reasons: -NR- (CnH2nNR) x-A- in which the symbol R represents a hydrogen atom or an alcohol radical that has from 1 to 4 carbon atoms, the symbol n represents an integer equal to or greater than two, the symbol x represents an integer from 1 to 7, the different symbols R of the CnH2nNR groups may be identical or different when x is greater than 1, and symbol A represents a divalent radical chosen from the radicals of formulas -CO-, -CS-, -CO-Q-, -CO-Q'-CO- in which the symbol Q represents an alcoholic radical having 2 to 6 carbon atoms and the symbol Q'a divalent, linear or branched organic radical, saturated or unsaturated, with epihalohydrins or compounds comprising at least one halohydrin function.
