PULP MIXTURE

A pulp mixture includes a lignocellulosic material, water, lignin, an inorganic salt, and a copolymer including two or more structural units chosen from ethylene oxide units, propylene oxide units, (meth)acrylic acid units, ethyl acrylate units, and combinations thereof. The copolymer is free of sil...

More Information
Summary:A pulp mixture includes a lignocellulosic material, water, lignin, an inorganic salt, and a copolymer including two or more structural units chosen from ethylene oxide units, propylene oxide units, (meth)acrylic acid units, ethyl acrylate units, and combinations thereof. The copolymer is free of silicone-containing structural units and the lignin is present in an amount of greater than about 150 ppm, based on a total weight of the pulp mixture.
