Vinyl chloride - Wikipedia
It is also called vinyl chloride monomer (VCM) or chloroethene. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). Vinyl chloride monomer is among the top twenty largest petrochemicals ( petroleum -derived chemicals) in world production. [ 2 ]
Mechanism and type of polymerization of chloroethene
Nov 6, 2021 · Ethene reacts with hydrogen chloride to form a monomer used in the production of a polymer. This monomer is chloroethene. How is the polymer formed from the monomer? Is this an addition or a condensation polymerization?
The Polymerization of Ethene - Chemistry LibreTexts
Jan 23, 2023 · In an ethene molecule, CH 2 =CH 2, the two pairs of electrons which make up the double bond aren't the same. One pair is held securely on the line between the two carbon nuclei in a bond called a sigma bond. The other pair is more loosely held in an orbital above and below the plane of the molecule known as a π π bond.
Chloroethene - an overview | ScienceDirect Topics
PVC is made by the polymerisation of vinyl chloride (chloroethene) which is itself made by the chlorination of ethene. The chlorine atoms on the carbon backbone chain account for the much higher weight per unit volume of PVC compared to the polyolefins (see Table 13.5 ) and their syndiotactic arrangement means that the polymer is largely ...
Polymerization of Alkenes - Chemistry LibreTexts
Jan 23, 2023 · This page looks at the polymerisation of alkenes to produce polymers like poly (ethene) (usually known as polythene, and sometimes as polyethylene), poly (propene) (old name: polypropylene), PVC and PTFE. It also looks briefly at how the structure of the polymers affects their properties and uses.
Poly(chloroethene) (Polyvinyl chloride) - Essential Chemical …
Poly(chloroethene), usually known as polyvinyl chloride or just PVC, is the most versatile plastic and, after poly(ethene), the most widely used. The variety of uses comes from its ability to be formulated with different additives and with different molecular masses, giving plastics that range from rigid to pliable.
Addition polymerisation - Organic chemistry - (CCEA) - BBC
The C=C double bond in ethene is involved in the polymerisation reaction. It allows ethene molecules to join, so it is an example of an addition reaction>. Poly (ethene) is an addition polymer ...
A. Polymerization: Cationic Polymerization - University of Texas …
Consequently, radical polymerization is one of the more general methods of polymerization. In fact, even ethylene is readily polymerized to give the familiar polymer poly(ethylene). The mechanism of radical polymerization is illustrated below for the polymerization of …
Addition polymers are macromolecules, long chain covalent molecular structures consisting of repeating units. In a copolymer there is more than one repeating unit, whereas homopolymers, eg poly(chloroethene) (PVC), consist of only one.
Addition Polymerisation | CIE A Level Chemistry Revision Notes 2022
Jun 25, 2021 · The repeating units of poly (ethene) and poly (chloroethene) are similar to their monomer except that the C=C bond has changed into a C-C bond. Worked example: Identifying monomers. Answer 1: When ethenol (CH (OH)=CH 2) is polymerised, the C-C double bond opens to produce a repeating unit of CH (OH)-CH 2. This gives the polymer poly (ethenol)
