The polymers are linear and so are potent. The monomers are primarily organized head-to-tail, this means that chloride is located on alternating carbon centres. PVC has mostly an atactic stereochemistry, meaning which the relative stereochemistry from the chloride centres are random. Some degree of syndiotacticity with the chain presents a couple of per cent crystallinity that's influential within the Qualities of the material.
سوزاندن، تولید و آزادسازی مقدار زیادی دی‌اکسین است و اجزای تشکیل‌دهندهٔ کلرین که محیط زیست را می‌آلاید.
The molecular structure of PVC is made of a long-chain polymer with repeating vinyl chloride models. Just about every vinyl chloride device includes one particular carbon atom double-bonded to your chlorine atom and solitary-bonded to two hydrogen atoms.
PVC features a list of exclusive properties that add to its wide selection of applications. One of many main features is its durability and resistance to environmental stressors for instance moisture, substances, and ultraviolet radiation.
