Antistatic compound

Even in polymer chemistry these species may be of interest since more and more attention is devoted to polymerization in confined volumes, such as micelles, whereby the graft copolymer could first help in the emulsion polymerization of a monomer compatible with the backbone and subsequently act as a surface modifier of the polymer formed (wetting agent, pigment binder, coating binder, antistatic compound, adhesion factor, etc.). 

A. Ea r farocessing of yams and fibers in all steps of the textile-manufacturii fvocedure. In this case the treatment can be restricted to tl addition of antistatic compounds to the spin-finishing bath. These compounds do not necessarily have to be wash-proof. 

PEs comes in a range of densities, of which those relevant to RPs are low density PE (LDPE) and high density PE (HDPE). PE is rarely encountered as a matrix for RPs, though it forms a useful neutral carrier for specialty concentrates and master batches, for pigments, conductive/ antistatic compounds, and other specialties. Recent work, however, has produced high-performance PE fibers that are targeted to have a useful role to play in the future, as reinforcing materials (Chapter 2).

Two specific examples of antistatic compounds which can be used internally or applied as a solution are (3-lauramidopropyl)trimethyl-ammonium methyl sulfate, for use in PVC, polystyrene, polythene and ABS and stearamidopropyldimethyl-2-hydroxyethyl ammonium nitrate, as a 50% solution in an ispropanol-water mixture, for use in PVC. 

Some Pebax grades are used to enhance the characteristics of other thermoplastics, in particular as antistatic agents, since they naturally disperse electrostatic charges, and as such can be added to a large number of thermoplastic matrices (acrylonitrile-butadiene-styrene (ABS), polystyrene, polyoxy-methylene (POM), polyvinylchloride (PVC), polymethylmethacrylate (PMMA) and polycarbonate (PC)) to impart permanent antistatic properties, whatever the ambient relative moisture or surface friction they may be subjected to. These antistatic compounds are suitable for countless applications in office and electronic equipment (photocopier components, printer components, etc.) as well as in technical packaging,...
