る。(Prior art) Polyvinylidene fluoride is a resin with a high specific gravity, good drainage, low refractive index, excellent impact resistance and light resistance, and relatively high transparency, so it is used as monofilament for fishing lines and fishing nets. It has been put into practical use in many cases as
4-5359, Special Publication No. 43-13399). However, these polyvinylidene fluoride monofilaments also have the disadvantage of relatively low knot strength.

る。 。As is well known, many fishing lines are currently made of polyamide (nylon type) or polyester, but the drawbacks are that they have a low specific gravity and are difficult to sink, and they also have water absorption properties, so the lines can become tangled and easily underwater. The reduction in strength is considered to be a major problem. From this point of view as well, polyvinylidene fluoride monofilaments play an important role, and increasing the knot strength, which is known as the drawback mentioned above, is considered to be the key point in providing excellent fishing lines. As a means to increase knot strength, 1. Method of blending acrylic resin with vinylidene fluoride resin (JP-A-54-1
06622), a method of applying heat treatment during two-stage stretching after melt spinning (Japanese Patent Publication No. 43-13399, Japanese Patent Application Laid-Open No. 60-18

の樹脂組成物ができる。The specific fluorine-containing copolymer used in the present invention is a vinylidene fluoride copolymer having at least hexafluoroacetone in the molecular chain, and the ether bond due to the hexafluoroacetone unit is present in the molecular chain. It is distinguished from other fluoroolefin-based vinylidene fluoride copolymers by its presence in . That is, the composition as described above gives the molecular chain great flexibility, resulting in a monofilament resin that also has rubber-elastic properties. In addition, the fluorine-containing copolymer is a low-crystalline polymer and has many vinylidene fluoride units in its molecules, so it has excellent compatibility with vinylidene fluoride homopolymer, and by blending the two, tensile strength A new type of resin composition can be produced that has high strength and knot strength, excellent transparency, and elasticity.

溶性も低下する。The hexafluoroacetone content in the fluorine-containing copolymer is preferably 2 to 15 mol%. If it is less than 2 mol %, the polyether properties will not be sufficiently developed, and if it is more than 15 mol %, it will become too soft and sufficient strength will not be obtained. Further, when tetrafluoroethylene and/or trifluoroethylene is contained as a third component, it is preferably 0 to 30 mol%. When the content of the third component exceeds 30 mol%, crystallization of vinylidene fluoride and tetrafluoroethylene and/or trifluoroethylene is promoted, which not only reduces transparency but also causes compatibility with the vinylidene fluoride homopolymer. Solubility also decreases.

がる。The fluorine-containing copolymer described above can be blended in an amount of 5 parts by weight or more to 100 parts by weight of vinylidene fluoride homopolymer, but the tensile strength and stretchability of the monofilament may be controlled depending on the blend composition. Ru. If it is less than 5 parts by weight, the properties of the vinylidene fluoride homopolymer will be dominant and the knot strength will not be improved sufficiently, so 5 to 100 parts by weight is preferred, and if it is more than 100 parts by weight, PVDF crystals will gradually form. This leads to a decrease in strength and strength.
