Key words: carbon dioxide, N- izopropilakrilamid (NIPAM), NTBA, AIBN, solubility, gas expanded liquids, solubility isotherms

The solubility isotherms of N-tert-butylacrylamide (NTBA) monomer and azobisisobutyronitrile (AIBN) initiator for radical polymerization in carbon dioxide at temperatures and pressures ranging from 0.1 to 40.0 MPa and 305.0 to 353.2 K were determined using synthetic visual methods. The maximum concentrations of NTBA and AIBN at these conditions were determined. The phase behavior patterns of low-molecular weight compounds with low melting points in CO₂ were discussed. It’s shown that AIBN solubility doesn’t limit the range of conditions for the polymerization process using NTBA.
