Abstract—Effect of Tsinkamin-02 additive on characteristics of electrolytically fabricated zinc electrode for
backup power sources was studied. Its inﬂ
uence on how a zinc powder is formed, deposition process parameters
(current efﬁ ciency by zinc, cathodic polarization), and utilization factor of the active substance of the negative
electrode in a nickel–zinc power source discharged in a high-intensity mode was determined. The component
concentrations of the electrolyte used to deposit the zinc powder were optimized. An explanation was suggested
for the mechanism of Tsinkamin-02 action.
The possibility of involving 1-(N-allyl-pyridinium-
4-yl)-2-(4-pyridyl)ethylene bromides and 1,2-bis(N-
allyl-pyridinium-3-yl)ethylene dibromide in the radical
polymerization was investigated. It was found that all
investigated substituted ethylenes are practically not
homopolymerized under free radical initiation, however
mide enters copolymerization with N-vinylpyrrolidone
and acrylonitrile to form a statistical copolymers. Kinetic
regularities of the reaction were examined and the relative
activities of the monomers were determined. The structure
of the obtained polymers was also determined.
Copolymerization reaction allows extensive modiﬁ -
cation of the properties of macromolecular compounds.
Involvement of substituted ethylenes in the copolymeriza-
tion is undeniable interest. On the one hand, the nature
of the substituent effect can be clariﬁ ed on the reactivity
of the vinyl compound, with the other, the synthesis of a
large number of different copolymers with new valuable
properties can be performed. Quaternized nitrogen-con-
taining heterocyclic systems are well-known as biologi-
cally active substances, therewith many of them possess
antimicrobial properties [1–6].
We have investigated the possibility of obtaining
a homo- and copolymers of 1-(N-allyl-pyridinium-
3-yl)-2-(3-pyridyl)ethylene bromide (3-APPEB),
bromide (4-APPEB) and 1,2-bis(N-allyl-pyridinium-3-yl)
ethylene dibromide (3-DAPPEB) from N-pyrrolidone and
N-vinylpyrrolidone (VP) and acrylonitrile (AN).
3-APPEB and 4-APPEB bromides were synthesized
by allylation of 3- and 4-dipyridy
lethylene according to
