What type of bond does polyvinyl chloride have?
Polyvinyl chloride (PVC) is a type of polymer that is made up of repeating units of vinyl chloride. The bond in PVC is a covalent bond, where atoms share electrons to form a strong bond within the polymer chain structure.
Why PVC is soft and flexible whereas bakelite is hard and brittle?
PVC is softer and flexible because it is a thermoplastic polymer, which means it can be easily molded and reshaped when heated. Bakelite, on the other hand, is a thermosetting polymer, which means it hardens irreversibly once molded and cannot be reshaped. This makes bakelite hard and brittle compared to PVC.
What is the chemical bond of PVC?
Polyvinyl chloride (PVC) is a polymer made up of repeating vinyl chloride monomers. The chemical bond in PVC is a covalent bond between the carbon and chlorine atoms in the vinyl chloride monomers. This covalent bond is strong, giving PVC its durability and resistance to heat and chemicals.
Is PVC a compound or mixture?
PVC is a compound, not a mixture. It is made up of long chains of repeating units of vinyl chloride molecules, which are chemically bonded together to form a single substance with consistent properties.
What is the chemical structure of polymer clay?
Polymer Clay is basically polymer vinyl chloride, a type of plastic. There are ground up pigments as well as a liquid plasticizer- all clay manufacturers have a "secret formula" that they won't share with the public. The main thing to remember is that when you fire the clay in the oven, you are "burning out" the plasticizer that is liquid, and all that is left is the pigment and the PVC which bonds together in the low heat.
What is PVC plastics?
Polyvinyl chloride, (IUPAC(chloroethanediyl)) commonly abbreviated PVC, is a thermoplastic polymer. It is a vinyl polymer consisting of vinyl groups (ethenyls) that are bound to chlorine.
Is vinyl the same as PVC?
No, vinyl and PVC are not the same. Vinyl is a type of plastic resin, while PVC (polyvinyl chloride) is a synthetic plastic polymer derived from vinyl. Vinyl can refer to a broader range of materials, while PVC specifically refers to a type of vinyl.
What makes PVC more flexible?
PVC can be made more flexible by adding plasticizers, which are molecules that increase the spacing between polymer chains, thus allowing them to move more freely. These plasticizers improve the polymer's flexibility and make it more resilient to bending and stretching. Additionally, the amount and type of plasticizer used can be adjusted to achieve the desired level of flexibility in the PVC material.
What is the systematic name of the polymer referred to above as PVC?
PVC or polyvinyl chloride is a polymer created from the alkene monomer vinyl chloride (CH2=CHCl)
Is PVC natural or man-made?
PVC (polyvinyl chloride) is a man-made synthetic plastic material. It is produced through the polymerization of vinyl chloride monomers, making it a type of plastic known as a vinyl polymer.
What is the solvent for PVC?
The solvent commonly used for PVC is tetrahydrofuran (THF). It is often used to dissolve PVC for various applications such as adhesive formulations or polymer processing.
What is the structural formula of the polymer used in PVC?
The chemical formula for PVC (polyvinylchloride) is [-CH2-CHCl-]n, where n is equal to ~60,000 to 140,000. Actual useful formulations of PVC also include a small percentage of various stabilizers to enhance the performance and prevent discoloration from light and heat.

How a PVC polymer might become degraded?
PVC polymers can become degraded through exposure to heat, UV radiation, or chemical agents. These factors can break down the polymer chains, leading to decreased mechanical strength, discoloration, and eventually structural failure. In the case of PVC, degradation can also release toxic byproducts such as hydrogen chloride gas.
What is the material on water pipes?
water pipes are almost always made of a polymer PVC (Poly Vinyl Chloride)... it is a linear polymer with 1-chloro ethene as its repeating unit...
