The polymerization of 2-naphthyl methacrylate (NM) in toluene in the presence of tetracyanoethylene and picric acid was studied dilatometrically. The overall activation energy for the polymerization was calculated both in the absence and in the presence of electron acceptors. The results (13.7 kcal/

β¦ Synopsis
A strong decrease in positronium yield is observed in ethanol (with isopropanol) and squalanc which contains admixtures of CSz and &Fe at falling temperature. The results are interpreted in terms of the spur reaction model ofpositroniurn formation with account taken of a free volume necessary for posiuonium localization.

## Abstract Coalescence of air bubbles is important in gasβliquid reactors and food processing operations. Bubbles can be stabilized by using nonβionic surfactants. Binary coalescence of air bubbles in ethylene glycol and aqueous glycerol solutions were studied in this work in presence of Span 80.
Abstrct-The presence of the redox couples (eg Fe(CN)z-/Fe(CN)iand 1\*/I-) in acidic solutions can have a substantial influence on both magnitude and stability of the photocurrent of polyaniline (PANi). Even at positive potentials PANi can be used to induce a marked photoelectrochemical reduction of
The solution polymerization of 2-methyl 2-oxazoline in the presence of microacceptors without or with polymerizable group (viz. 2,4,7-trinitrofluorenone and tetracyanoethylene) was studied. In the first case, the polymerization is first order with respect to both monomer and acceptor. For the second
Lifetime measurements of positrons in polar media have been made. It was suggested from the experiments that positrons are captured in liquid or amorphous media, owing to the strong dipolar electric field of polar groups which are free from surrounding molecules.
