Naming Vinyl Polymers

Vinyl polymers in the simplest case vinyl monomers are named by using the prefix poly in front of the monomer name e g.

Naming vinyl polymers.

The word polymer is derived from two greek words poly that means many numerous and mer which means units. A generic source based name comprises two parts. This leads to the formation of a polymer chain. An industrially important example is vinyl chloride precursor to pvc a plastic.

That is to join end to end forming a polyvinyl compound such as polyvinyl chloride. When a monomer name consists of more than one word or if the name. Poly vinyl chloride pvc ch 2 chcl n. A vinyl polymer is built from a monomeric vinyl.

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. Https engineers academy this video introduces different polymers and explains how their structures can be determined. These identical structures we understand as a unit made up of two or more molecules join together to form a long chain. 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. 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. Vinyl group blue color monomeric vinyl is able to undergo chain growth polymerization due to its unsaturation.

The molecules of two different compounds can also be made to link up forming a copolymer such as the plastic vinylite and the. 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. 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.

Which supports the name chain growth polymers is presented here. In the presence of an initiator the double bond can be broken and the monomer can be made active to attach with another monomer. Since polymers are traditionally divided into two main classes vinyl and non vinyl we shall examine the nomenclature of each class separately.
