摘要： A grafted polyvinyl alcohol polymer includes a polyvinyl alcohol main chain and a plurality of side chains grafted to the polyvinyl alcohol main chain. One or more of the side chains from the plurality of side chains include one or more units selected from: an aliphatic carboxylic acid, an aliphatic amide, an amino alkyl (meth)acrylate, a hydroxylated alkyl (meth)acrylate, or any combinations thereof. The grafted polyvinyl alcohol polymer can be included in a formulation that also includes water, and the formulation can be used as an adhesive in a creping process.

摘要： A grafted polyvinyl alcohol polymer has a balance between hydrophilicity and hydrophobicity. The grafted polyvinyl alcohol polymer has a chemical functionality that allows for adsorption onto the pulp fibers, polymer film formation upon drying, repelling water upon wetting, polymer film swelling and breaking for prolonged wetting by water. When incorporated into paper products, the polymer can provide a paper having improved wet strength, temporary water repellency, and/or is dispersible in aqueous solutions.
