Where Can I Get A Polymer Of Vinyl Chloride

Pvc comes in two basic forms.

Where can i get a polymer of vinyl chloride.

In the past vinyl chloride could get into food stored in materials containing pvc but the u s. Polyvinyl chloride ˌ p ɒ l i v aɪ n əl ˈ k l ɔːr aɪ d. Kanevinyl m series which is a vinyl chloride vinyl acetate copolymers has outstanding fluidity in its molten state and is suited to processing at low temperatures. Polyvinyl chloride denoted as pvc is a synthetic polymer produced by the monomer vinyl chloride.

About 13 billion kilograms are produced annually. Vinyl chloride is an organochloride with the formula h 2 c chcl that 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. Government now regulates the amount of vinyl chloride in food packaging materials. In the production of pvc an addition polymerization takes place by arranging the monomers in head to tail fashion.

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. Due to the hazardous nature of vinyl chloride to human health there are no end products that use vinyl chloride in its monomer. When less than about 1 ppm of vinyl chloride is trapped in pvc packaging vinyl chloride in detectable amounts does not enter food by contact with these products. Vinyl chloride monomer left 3 and polymer right 4 one method for producing vinyl chloride is to first produce dichloroethane c 2 h 4 cl 2 by chlorinating ethene c 2 h 4 dichloroethane is heated and decomposed in a process known as thermo cracking to form vinyl chloride monomer c 2 h 3 cl and.

5 18 60 61 these polymers have been used extensively in the past for corrosion protective systems but they often need large amounts of strong solvents to be apply properly. It can be used either as a base. Vinyl chloride is a chemical intermediate not a final product. 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.

It also has excellent stretch properties at high temperature making it ideal as a material for secondary processing such as vacuum molding. Rigid sometimes abbreviated as rpvc and flexible. Chloride is highly flammable 4 toxic 2 and reactive 2 2.
