Acrylonitrile copolymer resins Chemische Eigenschaften,Einsatz,Produktion Methoden
Verwenden
Polyacrylonitrile cannot be melt
processed because extensive decomposition occurs before any appreciable
flow takes place. Various copolymers in which acrylonitrile is the major
component are, however, melt-processable and several have been produced
commercially. Such copolymers are commonly referred to as nitrile resins.
The main reason for the development of these copolymers was their low gas
permeability and carbonated-beverage containers represented a large potential market. However, concern about the carcinogenicity of residual acrylonitrile has rendered uncertain the future use of nitrile resins as containers for
foodstuffs.
In addition to their outstanding gas-barrier properties, nitrile resins have
good resistance to most organic solvents (but not acetone and methyl ethyl
ketone) and acids and bases. Nitrile resins may be melt-processed by all the
usual methods, e.g. injection moulding, blow moulding and sheet extrusion.
Applications include containers for agricultural, automotive and household
products.
