  Polyvinyl chloride Summary
Polyvinyl chloride is produced by polymerization of the monomer vinyl chloride, as shown.
Polyvinyl chloride was accidentally discovered on at least two different occasions in the 19th century, first in 1835 by Henri Victor Regnault and in 1872 by Eugen Baumann.
According to the EPA, "vinyl chloride emissions from polyvinyl chloride (PVC), ethylene dichloride (EDC), and vinyl chloride monomer (VCM) plants cause or contribute to air pollution that may reasonably be anticipated to result in an increase in mortality or an increase in serious irreversible, or incapacitating reversible illness.

 Polyvinyl chloride processing - Patent 4336176
It is also highly desired that the polyvinyl chloride compound be substantially free of fatty acids as these compounds may form soaps thereby leading to unwanted lubricating effect and lack of clarity in clear articles.
The calendering operation is initiated by mixing the polyvinyl chloride resin with the organo-tin stabilizer and the partial ester in the required amounts and thereafter thoroughly mixing such composition together and heating prior to delivery to the calendering roll.
EXAMPLE II A fully formulated polyvinyl chloride composition is prepared as follows: 0.2 parts by weight of the partial pentaerythritol ester of Example I is blended together with 1.5 parts of dioctyltin diglycolate and 100 parts of polyvinyl chloride resin.

 Chlorinated polyvinyl chloride - Wikipedia, the free encyclopedia
Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin.
CPVC is PVC (polyvinyl chloride) that has been chlorinated via a free radical chlorination reaction.
This reaction is typically initiated by application of thermal or UV energy utilizing various approaches.

 BuildingGreen.com - EBN 3:1 - Should We Phase Out PVC?
Vinyl chloride, commonly referred to in the industry as VCM (for “vinyl chloride monomer”), is a gas at normal temperature and pressure.
Vinyl chloride is stirred into water, together with small amounts of methyl cellulose and organic peroxides, agents that initiate polymerization and keep the polymerized particles from conglomerating.
The realization that vinyl chloride tended to leach into food or water from PVC containers, combined with the discovery that it is carcinogenic, have led to strict controls on the amount of residual vinyl chloride in PVC, especially containers for food and water.

 What is Polyvinyl Chloride?
Polyvinyl chloride, better known as PVC or vinyl, is an inexpensive plastic so versatile it has become completely pervasive in modern society.
Polyvinyl chloride should not be burned, as it can release harmful gas, and recycling is difficult because of the diverse additives used in various products.
Though polyvinyl chloride products have been used without apparent problems to human health for many years, the concern is that growing toxic waste created by the process, possible leeching, and PVC's non-biodegradable status will eventually and inevitably lead to problems that could be catastrophic.
