Uses
PVDC has a number of
applications, including molding resins, extrusion resins,
multilayer film, rigid barriers, containers, lacquer resin,
vinylidene chloride copolymer latex and foams, resins for
solvent coating, lattices for coating, and pipes for chemical
processing.
Definition
ChEBI: 1,1-dichloroethene is a member of the class of chloroethenes that is ethene in which both of the hydrogens attached to one of the carbons are replaced by chlorines. It has a role as a mutagen, a carcinogenic agent and a mouse metabolite.
Production Methods
PVDC polymerizes by both ionic and free-radical reactions.
Free-radical polymerization of PVDC may be by solution,
slurry, suspension, and emulsion methods. In copolymerization,
usually one component is introduced to improve the
processability or solubility of the polymer; others are added
to modify specific properties. Properties modified by copolymerization
depend on the content of components (structure,
amounts, and types).
Industrial uses
Because of its relatively low solubility anddecomposition temperature, Vinylidene Chloride Latex is widely used in the form of copolymerswith other vinyl monomers, such as vinyl chloride.The copolymers are employed as packagingfilm, rigid pipe, and as filaments for upholsteryand window screens.
