  • polyvinyl chloride
  • Polymer of vinyl chloride; tasteless, odourless; insoluble in most organic solvents; a member of the family of vinyl resins.
Abstract from DBPedia
    Polyvinyl chloride (alternatively: poly(vinyl chloride), colloquial: polyvinyl, or simply vinyl; abbreviated: PVC is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used in making plastic bottles, non-food packaging, food-covering sheets and plastic cards (such as bank or membership cards). It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is also used in plumbing, electrical cable insulation, imitation leather, flooring, signage, phonograph records, inflatable products, and many applications where it replaces rubber. With cotton or linen, it is used in the production of canvas. Pure polyvinyl chloride is a white, brittle solid. It is insoluble in alcohol but slightly soluble in tetrahydrofuran.

    ポリ塩化ビニル(ポリえんかビニル、polyvinyl chloride、PVC)または塩化ビニル樹脂とは合成樹脂(プラスチック)の1つで、塩化ビニル(クロロエチレン)の重合反応で得られる高分子化合物である。塩化ビニール、塩ビ、ビニールなどと略される。軟質ポリ塩化ビニルは、ソフトビニール(Soft Vinyl)、ソフビとも呼ばれる。しかし「ポリ」または「樹脂」を略した呼称は、その原料である単量体の塩化ビニルと混同するため、単量体の塩化ビニルを特に塩化ビニルモノマー (vinyl chloride monomer, VCM)と呼んで区別している。焼却によりダイオキシン類が発生するとして、懸念が示されたことがある。
