These identical structures we understand as a unit made up of two or more molecules join together to form a long chain.
Naming vinyl polymers.
An industrially important example is vinyl chloride precursor to pvc a plastic.
The word polymer is derived from two greek words poly that means many numerous and mer which means units.
Vinyl polymers in the simplest case vinyl monomers are named by using the prefix poly in front of the monomer name e g.
That is to join end to end forming a polyvinyl compound such as polyvinyl chloride.
The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms.
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.
Both the iupac and chemical abstracts service cas make similar naming recommendations for the naming of polymers.
Vinyl compounds contain the hydrocarbon vinyl group ch 2 ch.
This leads to the formation of a polymer chain.
In addition you will learn about di.
In basic terms a polymer is a long chain molecule that is composed of a large number of repeating units of identical structure.
Indeed cases of explosively uncontrolled polymerizations have been reported.
In the presence of an initiator the double bond can be broken and the monomer can be made active to attach with another monomer.
A generic source based name comprises two parts.
A vinyl polymer is built from a monomeric vinyl.
The molecules of two different compounds can also be made to link up forming a copolymer such as the plastic vinylite and the.
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.
When a monomer name consists of more than one word or if the name.
Poly vinyl chloride pvc ch 2 chcl n.
Since polymers are traditionally divided into two main classes vinyl and non vinyl we shall examine the nomenclature of each class separately.
The molecules of a single vinyl compound can be made to polymerize.
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.
Which supports the name chain growth polymers is presented here.
