摘要： Monofilaments comprising resin compositions which contain 1% by mass or more of a comonomer component (for example, hexafluoropropylene), have an intrinsic viscosity of 1.3 dl/g or more and a melting point of 165° C. or higher and contain a PVDF-based resin. Owing to the above composition and physical properties, the crystallinity and elastic modulus of the PVDF-based resin are altered. As a result, an appropriate flexibility can be imparted to the monofilaments while preventing deterioration in the mechanical properties.

摘要： A vinylidene fluoride resin having a weight-average molecular weight as relatively high as 300,000 or higher is mixed with a plasticizer and good solvent for the vinylidene fluoride resin to obtain a composition. A molten extrudate of the composition in a hollow-fiber membrane state is contacted, on its outer side, with a cooling liquid inert to the vinylidene fluoride resin to thereby cool the extrudate. During the solidification, the vinylidene fluoride resin is moderately and mildly crystallized. Thus, a hollow-fiber porous vinylidene fluoride resin membrane is produced which has a high crystallinity represented by an enthalpy of crystal melting 58 J/g or higher. The hollow-fiber porous membrane obtained is excellent in mechanical strength represented by tensile strength and elongation at break and in chemical resistance. It is effectively used as a water microfiltration membrane.

摘要： A porous membrane for water treatment of the present invention is made of a resin composition containing 100 parts by weight of a polyvinylidene fluoride based resin, and 5 to 13 parts by weight of a polyvinyl alcohol based polymer having a degree of saponification of 10 to 80 mol %. The porous membrane has a permeation wetting tension of 38 to 72 mN/m, and a tensile strength of 7 to 20 MPa, and thus is characterized by having the excellent mechanical strength and wettability. This is a porous membrane for water treatment essentially containing the polyvinylidene fluoride based resin, which allows water treatment to be highly efficiently performed on raw water (river water, industrial waste water, and the like), in particular. The porous membrane is manufactured, firstly, by melt-extruding a mixture composition containing a polyvinylidene fluoride based resin, a polyvinyl alcohol based polymer, a plasticizer, and a solvent, and then by extracting the plasticizer and the solvent from the substance thus extruded.
