Figure 13.10
Cloud pressures for PEG (5k) and the corresponding PCL block
copolymer (5k-b-11k) in near-critical trifluoromethane. The concen-
tration of polymer in solution was 1 wt%. Note: micelles are present
above the copolymer CP to over 1800 bar (the actual MP was beyond
the experimental pressure range). Re-plotted on the basis of data from
Green et al.

Figure 13.11
Cloud pressures for PEG (5k), PCL (12.6k), and the corresponding
block copolymer (5k-b-11k) in near-critical dimethyl ether. The
concentration of polymer in solution was 1 wt%. Note: micelles were
formed at a concentration of 2 wt% for a small region at lower
temperatures. Re-plotted on the basis of data from Green et al.
