Electrochemical polymerization of acetylenic derivatives. I. Anionic polymerization of phenylacetylene and diphenyldiacetylene

Effect of transition rate and propargyl alcohol concentration on the corrosion of carbon steel during transitions in fluid composition from inhibited hydrochloric acid to sodium chloride brine

“…5 in detail, it is perhaps prudent to review what is known about the mechanism of PA inhibition. The inhibition mechanism of PA can be divided into two steps, namely, chemi-sorption of the acetylenic alcohol and its derivatives on the metal surface followed by the formation of a protective film by polymerisation on the active metal surface [8,[25][26][27][28][29][30]. The polymerisation process is surface-catalysed and promoted by acidic conditions.…”

Polyarylacetylenes. Structure and properties

“…Kinetic plots for the thermal cis-Iruns isomerization of cis-transoidal PPA (hexachlorobutadiene solution).In our laboratories, PA was recently polymerized by an anionic electroinitiated method[42]. A year later, Subramanian et al[43] also published some results on electroinitiated polymerization of PA. A comparison of Subramanian's published spectral data and ours has shown that the PPA obtained has a high content of cyclohexadiene sequences, which in our opinion, could be obtained only by thermal induced reactions on a proprgating chain of a cis-polymer.…”
