Vinyl polymers is a name often used to identify polymers based on the vinyl group nch ch 2 but really has been used to identify polymers and copolymers of vinyl chloride.
Economical versatile polyvinyl chloride pvc or vinyl is used in a variety of applications in the building and construction health care electronics automobile and other sectors in products ranging from piping and siding blood bags and tubing to wire and cable insulation windshield system components and more.
For example polyvinyl chloride is an industrial homopolymer synthesized from repeating units of vinyl chloride.
Pvc comes in two basic forms.
Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year.
About 13 billion kilograms are produced annually.
Pvc is made by subjecting vinyl chloride to highly reactive compounds known as free radical initiators.
Vcm and water are introduced into the reactor and a polymerization initiator along with other additives.
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.
