Mechanisms controlling the nucleation kinetics in the foamed amorphous D,L-polylactide,
which is preliminary plasticized using sub-ical or supercritical carbon
dioxide, are established using analysis of videodata on the depressurization-induced
quasi-isothermal (313,3 K) foaming of the polymer. Possible scenarios of the phase
separation in the polylatide—carbon dioxide system at the stage, which precedes the
expressed foam formation, are considered.
