摘要： A vinyl alcohol polymer with a side chain being a hydroxyalkyl group having 2 to 20 carbon atoms is disclosed.
Conventional water-soluble vinyl alcohol polymers gives, where they have a high interfacial activity, an aqueous solution with much-foaming and hence a problem when used for commercial purposes. On the other hand, the vinyl alcohol polymer of the present invention gives, where it is water-soluble, an aqueous solution with less-foaming in spite of its high interfacial activity, and hence an excellent industrial applicability.
The vinyl alcohol polymer of the present invention is useful as thermoplastic resin and dispersion stabilizer. In addition, the vinyl alcohol polymer of the present invention is usable for various purposes, e.g. surfactants for various uses, paper coating agent, quality-improving agent for paper such as paper ingredients and pigment binders, adhesive for wood, paper, aluminum foil and inorganic materials, binder for nonwoven fabric, paint, warp sizing agent, fiber-processingagent, sizing agent for hydrophobic fibers such as polyester fiber, various films and sheets, bottles and fibers.
