Several ongoing scientific tests have expanded this chemistry, mainly throughout the chemical improvements of the polymeric substance. The chemical modification of PVC employing different resources being an Lively modifying agent is explained in this perform. The latter comprised grafting polymerizations, nucleophilic radicals, substitutions, PVC modifications, and elimination or dehydrochlorination. This standpoint addresses the key PVC reactivity tendencies and delivers an overview of PVC functionalization although analyzing the environmental implications of PVC by means of the prism of chemical recycling. As a result of extensive ongoing study, this chemistry is expanded, principally in the chemical variations of the polymeric compound. To further improve its Image-stability properties, broaden the programs of poly(vinyl chloride) (PVC), and investigate PVC-connected phenomena, several chemical modifications are already launched to PVC.

ポリ塩化ビニルの「ポリ」という言葉は、ポリマー（重合体）からきたもので、「たくさん」という意味があります。しかし、一般的に呼ばれている「塩ビ」は塩化ビニルではなく、ポリ塩化ビニルを指しているケースが多いので注意が必要です。
型のなかにある空気を吸い取り、大気圧で型に押し付ける手法を「真空成形」、大気圧ではなく圧縮空気で金型に押し付ける手法を「圧空成形」と呼びます。
در مقابل حرارت و نور نسبتاً ناپایدار بوده و هیدروژن کلرید از آن خارج می‌شود. این ماده اثرات زیان‌بخشی روی خواص اشیاء دم دست (اجزای الکتریکی) علاوه بر اثرات فیزیولوژیکی بر جای می‌گذارد. پی‌وی‌سی پلاستیکی سخت است که به‌وسیلهٔ اضافه کردن روان‌کننده‌ها نرم و انعطاف‌پذیر می‌شود. بیشترین مورد استفادهٔ آن فتالیت است.
