Chemical Titles, and readily available journals ending November 30, 1973. This period has seen a continued growth in the use of polarography and related electrochemical techniques to follow chemical reactions and to supplement other physical and spectral measurements for purposes of characterization. Interest in applications toward biochemical and pharmaceutical problems has also increased. There also appears to be renewed interest in utilizing polarographic and related electrochemical data to predict and follow organoelectrochemical synthesis.In this review the symbols cv, dc, ac, and op are used to identify cyclic voltammetry, direct current polarography, alternating current polarography, and oscillographic polarography, respectively. Also, no attempt was made to list all organic polarographic references.

“…The other process is vapor deposition polymerization (VDP), which involves pyrolytic cleavage of a dimer and polymerization upon condensation. Many polymers with high Tg have been synthesized by the ECP process (7)(8)(9)(10)(11)(12). But there are few reports for synthesizing high temperature polymers by the VDP process.…”

Poly(para‐xylylene)(PPX)/carbon fiber towpregs were produced by two different in‐situ polymerization processes: Electrochemcal polymerization (ECP) and vapor deposition polymerization (VDP). The monomer used for the ECP process was α, α′ ‐dibromo‐para‐xylylene and di‐para‐xylylene was the starting material for the VDP process. A series of tests, including FTIR, WAXD, DSC, TG, and SEM were carried out to identify and compare these two composite towpregs. It has been confirmed that the PPX samples obtained by the two different polymerization processes were basically chemically identical. However, the polymer coating on the fiber surface produced by the VDP process was much smoother than that produced by the ECP process, which produced a porous coating.

A study has been made of the electro-and photo-initiated polymerization of N,N'-(4,4-sulfonyldipheny1ene)dimaleimide (4) in the presence of zinc dibromide and toluene. Product yields were linearly dependent on the photo irradiation or current passage times. The reaction mechanism appears to be a 2n+2lc cycloaddition resulting in the electro or photo condensation of 4. ZUSAMMENFASSUNG:Bei der elektro-oder fotochemisch initiierten Polymerisation von N,N'-(4,4'-sulfonyldi-pheny1en)dimaleinsaureimid (4) in Gegenwart von Zinkdibromid und Toluol nehmen die Umsatze linear mit der Bestrahlungs-oder Stromeinwirkungszeit zu. Der Reaktionsmechanismus scheint in einer 2n + 2lc-Cycloaddition zu bestehen, welcher zu einer Elektrooder Photo-Kondensation von 4 fuhrt.
