Abstract:
1. A method of inhibiting the deposition of organic contaminants in pulp or papermaking systems comprising adding to the pulp or papermaking system an effective deposition inhibiting amount of a hydrophobically modified poly[ethylene glycol] composition comprising the formula: wherein R wherein said hydrophobically modified poly[ethylene glycol] composition is derived from the reaction of a polyethylene glycol and a hydrophobic reagent, the reagent selected from the group consisting of a ketene dimer, a glycidyl ether and alkenyl succinic anhydride; and wherein the viscosity of a 5 wt % concentration of the hydrophobically modified poly[ethylene glycol] composition is from about 1 cP to about 10,000 cP.
