Epichlorohydrin-based polymers containing primary amino groups used as additives in papermaking

Disclosed is a method for manufacture and application of a polymeric papermaking additive, which can be used in paper manufacture as an agent for improving retention, drainage, product strength and paper machine operation. The additive according to this disclosure is a polymer of epichlorohydrin and contains primary amino groups. Under neutral or acidic conditions these primary amino groups become cationic, which assures good adsorption of the polymer onto anionic fibres and fines of pulps used for production of paper or paperboard. By adsorbing on several fibres or fines, the polymer can increase the retention of fines and fillers. Primary amino groups of this polymer can also form chemical bonds with carbonyl groups of cellulose, lignin and hemicellulose, which are especially abundant in the fibres and fines of mechanical pulps. The cross-linking of fibres and fines by chemical bonds can increase the initial strength of wet web and the strength of rewetted paper. Mechanical pulps contain high negative charge and tend to deactivate many conventional cationic polymers. Because of its high cationic charge and the ability to form chemical bonds with mechanical pulp, novel papermaking additive according to this invention is particularly suitable for improving the retention and the strength of paper made from fibrous pulp suspensions that contain at least a portion of mechanical pulp. If the polymer has a high molecular weight it can be use as a single component retention and strength additive. If the polymer has a relatively low molecular weight, it can be conveniently used as coagulant and can be combined with a high-molecular-weight, low-charge-density polymer that serves as a flocculent.

The amount of difunctional crosslinker used is based on the polyamidoamine amine number and reduced specific viscosity (RSV). The PAE resin is prepared by first synthesizing a polyamidoamine from a polyamine and a polycarboxylic acid or polycarboxylic acid derivative, wherein the polyamine is present in a molar excess, said molar excess being from about 1.02 to 2.00, then reacting the polyamidoamine with difunctional crosslinker, wherein the weight % of difunctional crosslinker to polyamidoamine solids is no more than about 0.308(amine number/RSV) - 9.18 or 0,385(amine number/RSV) - 5.20, wherein the amine number is expressed as the milliequivalents of amine per gram of polyamidoamine solids and the RSV is the reduced specific viscosity measured at 2 % concentration in IM NH4CI expressed in deciliters per gram. PAE resins prepared according to this process can by used in creping adhesives, which are used to manufacture a variety of paper articles, such as facial tissue, bath tissue, wipes, paper towels, paper napkins, filter papers, and coffee filters.
