Health and Safety Executive. Vinylidene chloride (CH 2 =CCl 2), a clear, colourless, toxic liquid, is obtained from trichloroethane (CH 2 =CHCl 3) through the dehydrochlorination (removal of hydrogen chloride [HCl]) of that compound by alkali treatment.

For processing into PVDC, the liquid is suspended in water as fine droplets or treated with soaplike surfactants and dispersed in water as an emulsion of small particles.

Summary: Evaluates the environmental hazards and risks to human health posed by the production and use of vinylidene chloride. Vinylidene chloride/vinyl chloride copolymers are used for the packaging of foods, as metal coatings in storage tanks, building structures.

IARC published on its website a list entitled “Agents Classified by the IARC Monographs, Volumes 1 - " (IARC, ). IARC concludes that vinylidene chloride is classified in Group 2B (“possibly carcinogenic to humans”), and that there is sufficient evidence of carcinogenicity in animals for vinylidene chloride (Grosse et al., ).

This is the amount of vinylidene chloride which gave a chromatographic peak large enough to distinguish it from the leading edge of a contaminant peak present in the CS 2. (Section ) The detection limit of the overall procedure is µg per sample ( ppm or mg/m 3).boiling point: °C ( mm).

Vinyl and Vinylidene Chlorides Poly(vinyl chloride) is often highly plasticized to improve rheology for melt processing. It is highly susceptible to UV and high-temperature degradation and stabilizers (see Stabilizers in the Polymer Additives section) are commonly added.

for the analysis of 36 samples over the range 12 to 85 µg vinylidene chloride per sample. Desorption efficiency was determined to be 80% for a loading of 7 µg vinylidene chloride at a vinylidene chloride concentration of 10 mg/m3 and high relative humidity; the breakthrough volume was L when sampling at L/min from this atmosphere.

There is disclosed expandable vinylidene chloride-based resin particles comprising parts by weight of a non-crystalline vinylidene chloride-based resin composition and 1 to 40 parts by weight of a volatile organic blowing agent or a composition thereof, said resin composition consisting of a tetrahydrofuran-soluble component [A] which is a random copolymer having a weight-average molecular Cited by: Cite this entry as: () Poly(vinylidene fluoride).

In: Gooch J.W. (eds) Encyclopedic Dictionary of Polymers. Springer, New York, A thermoplastic polymer that is commonly called saran. Polyvinylidene chloride forms films that are impermeable to vapors, moisture, and oxygen. It is most often used as a barrier film for packaging.

Peroxidizable monomer, such as VINYLIDENE CHLORIDE, may initiate exothermic polymerization of the bulk material [Bretherick p.].

Mixing vinylidene chloride in equal molar portions in a closed container with any of the following substances caused the temperature and pressure to increase: chlorosulfonic acid, nitric acid, or oleum. Measured steady state levels of vinylidene fluoride in blood of mice increased with increasing exposure concn.

For both and ppm vinylidene fluoride exposures, the experimentally determined data fell within the 95% confidence interval predicted by the physiological model. Vinylidene definition: of, consisting of, or containing the group CH 2:C | Meaning, pronunciation, translations and examples.

Vinylidene chloride was not detected in any of the raw water samples, and only one finished water sample collected during the summer months (Aug.- Sept.) showed a mean concentration of less than 1 }ig/l and a maximum concentra- tion of 20 p.g/1 for vinylidene chloride.

PVDC has characteristics ideal for food packaging because it has low permeabiltiy to water vapor and gasses.Vinylidene chloride is a central nervous system depressant. Repeated exposure to low concentrations of vinylidene chloride may cause liver and renal dysfunction (Torkelson & Rowe, ).

Skin contact with vinylidene chloride causes irritation, which may be due partly to the presence of an inhibitor, hydroquinone monomethyl ether (Chivers, ).
