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
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 peroxodisulfate.

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 po
Photochemical reactions of some haloheterocycles bearing electron-withdrawing groups 1a-d with electron-poor olefins 2a-c gave the addition products 3a-f and 3h-m in good yields. Other products obtained were the corresponding olefins 4a-k and the alkanes 3g. These reactions involve homolytic cleavag
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
PAN1 6lms of thicknesses from 0.06 to 7~ were investigated by the potentiostatic pulse method and EIS. The 6hns behaved very similar in respect to both methods over the whole range of thicknesses. The oxidii fIhn can be described as a battery electrode with a specific capacity as high as 130Fcmm3. T
