What is the structural formula of the monomer of PVC?
Some Common Addition Polymers
| Name(s) | Formula | Monomer |
|---|---|---|
| Poly(vinyl chloride) (PVC) | –(CH2-CHCl)n– | vinyl chloride CH2=CHCl |
| Poly(vinylidene chloride) (Saran A) | –(CH2-CCl2)n– | vinylidene chloride CH2=CCl2 |
| Polystyrene (PS) | –[CH2-CH(C6H5)]n– | styrene CH2=CHC6H5 |
| Polyacrylonitrile (PAN, Orlon, Acrilan) | –(CH2-CHCN)n– | acrylonitrile CH2=CHCN |
What type of bond is PVC?
PVC consists of polar molecules which are attracted to each other by dipole-dipole interactions due to electrostatic attractions of a chlorine atom in one molecule to a hydrogen atom in another atom: These considerable intermolecular attractions between polymer chains make PVC a fairly strong material.
Is PVC linear or branched?
Introduction to Plastics and Polymers Polyethylene, PVC, nylon 66, and polymethyl methacrylate are some linear commercial examples found in this book. Branched polymers can be visualized as a linear polymer with side chains of the same polymer attached to the main chain.
What is the molecular structure of plastic?
Structure. Most plastics contain organic polymers. The vast majority of these polymers are formed from chains of carbon atoms, with or without the attachment of oxygen, nitrogen or sulfur atoms. These chains comprise many repeating units formed from monomers.
What intermolecular forces are present in PVC molecules?
The main van der Waals forces in PVC are dipole-induced dipole forces. van der Waals forces include dipole-dipole, dipole-induced dipole, and London dispersion forces. The most important forces in PVC are dipole-induced dipole attractions. PVC is a polymer of vinyl chloride.
What is branched structure?
Branched polymers are defined as having secondary polymer chains linked to a primary backbone, resulting in a variety of polymer architectures such as star, H-shaped, pom-pom, and comb-shaped polymers.
Is PVC linear?
Some of the common examples of linear polymers are polyethylene, PVC, polystyrene, and polyamides. Linear polymers are generally more rigid.
What are the structure of the molecules and the types of bonds in plastics?
Specialty or Engineering Plastics A single polymer molecule may consist of hundreds to a million monomers and may have a linear, branched, or network structure. Covalent bonds hold the atoms in the polymer molecules together and secondary bonds then hold groups of polymer chains together to form the polymeric material.
What is PVC chemistry?
PVC is Polyvinyl Chloride. This is a plastic that has the following chemical formula: CH2=CHCl (see picture on the right).
