SYNTHESIS OF RE-PULPABLE TEMPORARY WET STRENGTH POLYMER FOR TISSUE APPLICATION
收藏官方服务：
资源简介：
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.
