A comparison between gravimetric and in-situ spectroscopic methods to measure t...
Duarte, Ana Rita C.; Anderson, L.; Duarte, Catarina M. M.; Kazarian, S. G.In situ ATR-IR spectroscopy was used to simultaneously measure the sorption and swelling of carbon dioxide at high pressures in a biocompatible acrylate copolymer poly(methylmethacrylate-co-ethylhexylacrylate-co-ethyleneglycoldimethacrylate), P(MMA–EHA–EGDMA). The ν3 band of CO2 dissolved in the polymer (at 2335 cm−1) was used to calculate the sorption data and the polymer swelling was determined by analyzing t...
