Nitromethane solubility parameter

In some cases the resolution of the solubility parameter into the three components p, and [14.31], [14.32], [14.34] is more suitable for explaining the experimental facts. For example, although the difference between the solubility parameters of the partially miscible solvent pair nitromethane-ethylene glycol is indeed small (A(5 = 3.5), both solvents differ greatly as regards their solubility parameter (5h (A(5h = 22.0). Many empirical results (e.g., the good miscibility of benzene and methanol) cannot, however, be explained by this approach. 

PECA is soluble in several highly polar solvents including nitromethane, DMF, acetone, tetrahydrofuran, and acetonitrile. Donnelly and Pepper have presented a more complete list of solvents and non solvents for polymethyl, polyethyl, and poly-n-butyl cyanoacrylate. These authors calculated the solubility parameter of PECA to be 11.2. Water absorption by PECA at room temperature and 50% RH is negligible.""...
