Poly vinyl chlonde

In the U.S.. poly(vinyl chlonde) is an EPA hazardous air pollutant under the Clean Air Act Section 112 (40 CFR 61) and is covered under the New Jersey Community Riglit-to-Know Survey N.J. Environmental Hazardous Substances (EIlS) List as chloroethylene. polymer with a reporting threshold of 225 kg (500 lb).

Copolymerization. Vinyl chloride can be copolymerized with a variety of monomers. Vinyl acetate, the most important commercial comonomer, is used to reduce crystallinity, winch aids fusion and allows lower processing temperatures. Copolymers are used in flooring and coatings. This copolymer sometimes contains maleic add or vinyl alcohol (hydrolyzed from the poly(vinyl acetate ) to improve the coating s adhesion to other materials, including metals, Copolymers with vinylidene chloride are used as barrier films and coatings. Copolymers of vinyl chlonde with acrylic esters in latex from are used as film formers in paint, nonwoven fabric binders, adhesives, and coatings. Copolymers with olefins improve thermal stability and melt flow, but at some loss of heat-deflection temperature,... 

Direct Potentiometry Detemdnatiou of Hydrogen Chlonde Gas. A system has been described for the continuous monitoring of the HCl levels in gases or aerosols using a chloride-ion-selective electrode [IS]. This arose from a study on the loss of volatile decomposition products from poly(vinyl chloride) (PVQ and other chlorocarbon polymers in simulated fires. The method works well because of the excellent solubility of HQ in water, and the fact that the chloride electrode senses only free Q ion. Thus, other volatile chloride compounds will not be sensed.
