Abstract: The invention relates to resin systems useful for imparting dry-strength to paper without substantially increasing the paper's wet-strength wherein the resin system comprises a cationic component and an anionic component. The invention also relates to the process for incorporating these resin systems into paper and the paper produced containing the resin systems.

Abstract: A method is provided for using an aqueous suspension of at least 15% of poly(ethylene oxide)(PEO) as a flocculent. PEO is dispersed in an aqueous solution of at least one salt selected from the group consisting of sodium or potassium formate, sodium or potassium hydroxide, sodium or potassium citrate, sodium or potassium acetate, sodium chloride or mixtures thereof to form a poly(ethylene oxide) suspension having at least 15% of poly(ethylene oxide) by total weigh.

Abstract: A method is provided for using an aqueous suspension of at least 15% of poly(ethylene oxide) (PEO) as a retention aid in the manufacturing of paper. PEO is dispersed in an aqueous solution of at least one salt selected from the group consisting of sodium or potassium formate, sodium or potassium hydroxide, sodium or potassium citrate, sodium or potassium acetate, sodium chloride or mixtures thereof to form a poly(ethylene oxide) suspension having at least 15% of poly(ethylene oxide) by total weigh. This suspension is dissolved in said dispersion in an aqueous system containing ferric ions or free chlorine; and said dissolved aqueous system is added to a pulp slurry for making paper just prior to forming the pulp into a wet web, whereby said aqueous suspension prevents the loss of fiber fines during the paper formation stage and resists viscosity loss due to ferric ions or free chlorine in the aqueous system.

Abstract: A paper-making furnish, comprising poly(paravinyl phenol), also known as poly(hydroxy styrene), in admixture with polyethylene oxide, and a process for retaining fine particles in paper-making comprising adding poly(paravinyl phenol) and polyethylene oxide to a paper-making furnish, are disclosed.

Abstract: A stabilized synthetic polyolefin pulp-cellulose blend is prepared by adding 0.1-1.0% by weight of an antioxidant (a hindered phenolic and/or phosphite antioxidant) to a solution of a polyolefin and solvent wherein the antioxidant is homogenously dispersed therein, forming the polyolefin into a polyolefin pulp, and then mixing the polyolefin pulp with from about 55 to about 90% by weight of a wood pulp to produce the blend. This blend with improved higher ignition temperature is used in the absorbent products industry as an absorbent core, when the blend is heated sufficiently to melt the polyolefin.

Abstract: Disclosed is a liquid-impermeable, gas-permeable nonwoven material comprising a thermally consolidated blend of (1) 5% to 30% of a first polyolefin pulp, (2) 15% to 90% of a second polyolefin pulp having a melting point at least 20.degree. C. higher than the first polyolefin pulp, and (3) 5% to 55% of a staple fiber. Also disclosed is a wet forming method for making such a nonwoven material without the use of surfactants.

Abstract: Disclosed are gelled aqueous compositions in brine solutions having a salt concentration from about 1% to about 10% at a pH of about 3 to about 11 having (a) a water thickening amount of an anionic partially hydrolyzed polyacrylamide and (b) a water-soluble cationic polyamide-epichlorohydrin resin in an amount sufficient to cause gelation and form the gelled composition. The compositions are useful in the recovery of oil and gas by fracturing and in enhanced oil recovery.
