Indeed cases of explosively uncontrolled polymerizations have been reported.
Naming vinyl polymers.
A vinyl polymer is built from a monomeric vinyl.
Vinyl polymers in the simplest case vinyl monomers are named by using the prefix poly in front of the monomer name e g.
An industrially important example is vinyl chloride precursor to pvc a plastic.
In the presence of an initiator the double bond can be broken and the monomer can be made active to attach with another monomer.
This leads to the formation of a polymer chain.
In chemistry vinyl or ethenyl abbreviated as vi is the functional group with the formula c h ch 2 it is the ethylene iupac ethene molecule h 2 c ch 2 with one fewer hydrogen atom.
1 polymer class generic name followed by a colon 2 the actual or hypothetical monomer name s always parenthesized in the case of a copolymer.
In addition you will learn about di.
The word polymer is derived from two greek words poly that means many numerous and mer which means units.
Vinyl compounds contain the hydrocarbon vinyl group ch 2 ch.
Iupac polymer nomenclature are standardized naming conventions for polymers set by the international union of pure and applied chemistry iupac and described in their publication compendium of polymer terminology and nomenclature which is also known as the purple book.
The molecules of a single vinyl compound can be made to polymerize.
Poly vinyl chloride pvc ch 2 chcl n.
A generic source based name comprises two parts.
In basic terms a polymer is a long chain molecule that is composed of a large number of repeating units of identical structure.
The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms.
When a monomer name consists of more than one word or if the name.
The molecules of two different compounds can also be made to link up forming a copolymer such as the plastic vinylite and the.
That is to join end to end forming a polyvinyl compound such as polyvinyl chloride.
Https engineers academy this video introduces different polymers and explains how their structures can be determined.
Vinyl group blue color monomeric vinyl is able to undergo chain growth polymerization due to its unsaturation.
Since polymers are traditionally divided into two main classes vinyl and non vinyl we shall examine the nomenclature of each class separately.
Since a pi bond in the monomer is converted to a sigma bond in the polymer the polymerization reaction is usually exothermic by 8 to 20 kcal mol.
