Cloudpoint method

Cloudpoint method, wherein the appearance and disappearance of another phase is detected through changes in turbidity of the fluid. Both binodal and approximate spinodal curves can be measured.

In a recent work, formation of block multipolymers from radicalized VDC copolymer particulates has been demonstrated (Caneba et al., 2008). Using the two-stage stirred-tank reactor system (Fig. 4.2.1), recipes and conditions were generated using high-throughput experimentation methods. From cloudpoint experiments (Table 1.1.3), it has already been established that the solvent for the VDC polymerization via FRRPP process is azeotropic MEK/i-butanol.
