Migration studies of acrylonitrile from commercial copolymers

Migration experiments were designed and conducted to estimate the diffusivity of acrylonitrile (AN) in four commercial copolymers in contact with water: ABS-248, ABS-LGA, SAN, and CYCOLAC. A new analytical result was used that accounts for the nonuniform concentration profile of the AN due to desorp...

Zusammenfassung:Migration experiments were designed and conducted to estimate the diffusivity of acrylonitrile (AN) in four commercial copolymers in contact with water: ABS-248, ABS-LGA, SAN, and CYCOLAC. A new analytical result was used that accounts for the nonuniform concentration profile of the AN due to desorption before the start of the controlled experiment.
