Copolymerization of Vinyl Chloride by Organometallic Compounds
ABSTRACT The copolymerizations of vinyl chloride with o-olefin or acrylic compounds were investigated with organometallic compounds as catalysts. In general, organoaluminium compounds need to be treated with a complexing agent such as tetrahydrofuran prior to use. Otherwise the former reacts with polyvinyl chloride and loses its activity. The copolymer of vinyl chloride and propylene was thus o...
متن کاملCopolymerization studies of vinyl chloride and vinyl acetate with ethylene using a transition-metal catalyst.
Since the advent of Ziegler-Natta polymerization of ethylene, attempts have been made to extend coordination polymerization to commercially important monomers with polar functionality. In this study we examined the copolymerization of perdeuterated vinyl chloride (VC) and perdeuterated vinyl acetate (VA) with ethylene using a tridentate Fe(II) dichloride pyridine diimine metal catalyst. The res...
متن کاملWorker exposure to vinyl chloride and poly(vinyl chloride).
The National Institute for Occupational Safety and Health (NIOSH) in early 1974 began industrial hygiene studies of vinyl chloride exposed workers. Three VC monomer plants, three VC polymerization plants, and seven PVC fabrication plants were surveyed. V polymerization plant workers and workers in one job category in VC monomer plants were exposed to average levels above 1 ppm. The highest aver...
متن کاملVinyl chloride Toxicological overview
Vinyl chloride is readily and rapidly absorbed via inhalation, ingestion and through the skin At room temperature vinyl chloride is a gas, so inhalation is the major route exposure Following absorption, it is distributed through the body, with the highest concentrations found in the liver and kidneys, followed by the lungs and spleen Vinyl chloride is mainly metabolised in the liver int...
متن کامل281e Kinetic Modeling of the Vinyl Chloride Suspension Polymerization
The physical properties of the polymer product determine to a large extent its processability and applications. A large number of properties are directly related to the molecular mass distribution (MMD) of the polymer product. Besides the MMD, the polymer microstructure also plays an important role and influences to a large extent the thermal stability of the polymer product. Most of the therma...
