✦ Synopsis

Hypergolic liquid fuels known to undergo cationic polymerization at the preignition stage with red fuming nitric acid (RFNA) as oxidizer have been found to exhibit synergistic hypergolic ignition at zero and subzero temperatures. This accelerated ignition with lowering of temperature has been ascribed to negative activation energy usually associated with most cationic polymerization systems. The best ignition was obtained with blends of fuels consisting of norbornadiene and furfuryl alcohol which underwent strong cationic polymerization with protonic acids and possibly Diels-Alder addition to each other.

A series of vinyl polymers with L-valine and L-leucine residues, and related copolymers with N-isopropylac y l amide, were studied in aqueous solution at different temperatures (25,30 and 35Β°C) and at two ionic strengths (0.01 M and 0.1 M NaCl). The protonation behavior revealed great differences be
