    Abstract: A porous polymeric medium having a low affinity for amide group-containing and adjuvant-containing materials is provided comprising a porous polyvinylidene difluoride substrate and a surface-modifying polymeric material having a low affinity for amide group-containing materials formed in situ at and covalently bonded to the surface of the porous polyvinylidene difluoride substrate, the surface-modifying polymeric material being derived from a mixture of first and second monomers. The first monomer includes an unsaturated monofunctional monomer having at least one hydroxyl group and the second monomer includes an unsaturated monomer.

    Abstract: Articles comprise a body made of hydrophobic synthetic partially open-cell material at least partially covered with a layer of hydrophilic material. The body of each article is characterized by the fact that it has a specific surface at least equal to about 40 cm²/cm³, and at least about 25% of its internal and external surface has a surface energy at least equal to about 73 x 10⁻⁷ newton/meter. The articles find use as sponges, so-called suede type materials, and wiping clothes. The sponges may be used for wiping, cleaning and other household or industrial uses.

    Abstract: A hollow fiber microporous membrane of a polyolefin having a polyvinyl alcohol chemically bonded to the inner and outer surfaces of the hollow fiber membrane and the surfaces defining the pores thereof exhibits a good hydrophilic property as well as good chemical resistance, mechanical strength, water permeation performance and durability. This membrane has an average pore diameter of 0.01 to 5 µm and a porosity of 20 to 80%. The polyvinyl alcohol/polyolefin composition ratio is constant in the membrane thickness direction of the hollow fiber, the oxygen/carbon atomic ratio X on the outer surface of the hollow fiber microporous membrane is 10 to 50%, and the condition defined by the ratio X/2 ≧ Y is satisfied between said oxygen/­carbon atomic ratio X and the oxygen/carbon atomic ratio Y in the entire microporous membrane. The membrane is prepared by irradiating a hollow fiber microporous membrane of a polyolefin with ionizing radiations, reacting the membrane with vinyl acetate and then hydrolyzing the membrane.
