〔産業上の利用分野〕
本発明は、フッ化ビニリデン系共重合体の製造方法に関
し、特に耐衝撃性及び耐寒性に優れたフッ化ビニリデン
系共重合体を製造する方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for producing a vinylidene fluoride copolymer, particularly for producing a vinylidene fluoride copolymer having excellent impact resistance and cold resistance. Regarding the method.
ポリフッ化ビニリデン(以下、r PVdF Jと略す
ことがある)は、耐候性、耐蝕性、電気的特性及び加工
性等に優れるため、多岐にわたる用途に使用されている
。Polyvinylidene fluoride (hereinafter sometimes abbreviated as r PVdF J) has excellent weather resistance, corrosion resistance, electrical properties, processability, etc., and is therefore used in a wide variety of applications.
しかし、PVdFは結晶性が大きいため、加工時の残留
応力が大きく、経時においてストレスクランクが生じ易
く、また柔軟性に欠け、耐衝撃性、耐寒性も他のフッ素
系樹脂に比して劣っている。そこで、耐衝撃性及び耐寒
性を改良するため、フッ化ビニリデンと他の単量体、例
えばヘキサフルオロプロピレン、テトラフルオロエチレ
ン、メチルメタクリレート、ブチルアクリレートなどと
を共重合する方法、あるいはPVdFにアクリル系樹脂
等を配合する方法等が提案されている。However, due to its high crystallinity, PVdF has large residual stress during processing, tends to cause stress cranks over time, lacks flexibility, and has inferior impact resistance and cold resistance compared to other fluororesins. There is. Therefore, in order to improve impact resistance and cold resistance, a method of copolymerizing vinylidene fluoride with other monomers such as hexafluoropropylene, tetrafluoroethylene, methyl methacrylate, butyl acrylate, etc., or a method of copolymerizing PVdF with acrylic Methods of blending resins and the like have been proposed.
しかし、フッ化ビニリデンと他の単量体とを共重合する
上記従来の方法によって得られる共重合体は、柔軟性に
は優れるが、融点が低下して使用可能な温度領域が低下
したり、加工性が悪化する問題がある。またPVdFに
アクリル系樹脂等を配合する方法によって得られる組成
物は、透明性、加工性及び柔軟性には優れるが、耐候性
及び耐薬品性が悪化する問題がある。However, although copolymers obtained by the above-mentioned conventional method of copolymerizing vinylidene fluoride and other monomers have excellent flexibility, they have low melting points and a reduced usable temperature range. There is a problem that processability deteriorates. Further, a composition obtained by blending PVdF with an acrylic resin or the like has excellent transparency, processability, and flexibility, but has the problem of poor weather resistance and chemical resistance.
そこで、本発明の目的は、PVdFが本来持つ特長とと
もに、耐衝撃性及び耐寒性に優れるフッ化ビニリデン系
共重合体を製造する方法を提供することにある。Therefore, an object of the present invention is to provide a method for producing a vinylidene fluoride copolymer that has excellent impact resistance and cold resistance as well as the inherent characteristics of PVdF.
