Electro‐ and photo‐initiated polymerization of <i>N</i>,<i>N</i>′‐(4,4′‐sulfonyldiphenylene)dimaleimide

SynopsisAnodic electroinitiated polymerization of acrylamide has been studied in DMF and DMSO in the presence of Co(NO,), or Co(CIO,), in the temperature range 25-40°C. The kinetics and mechanism of the process has been investigated as a function of variables and a suitable mechanism proposed. From the experimental observations, the rate of polymerization is seen to be proportional to [AM]',5, and [C2']'. Current densities exceeding 15 mA/cm2 have no effect on the rates. The average degrees of polymerisation ( p , ) increase with increasing [AM] and decreasing [Cg'] and applied current, I . It has been shown that a monomer-metal ion complex is oxidized at the anode, generating radical species. The polymerization and termination are confined to the anode compartment. The process is very efficient compared to the NO j mediated reaction.In view of the above we have studied the EIP of acrylamide in DMF and DMSO in the presence of COX,, where X-is nitrate or perchlorate. EXPERIMENTALAll reagents used were of AR grade. The solvents DMF, DMSO, and acetone were purified by standard methods.15 Acrylamide (AM) was recrystallized from chloroform and had an mp of 85°C. Co(NO,), -6H,O was a GR sample from S. Merck (India). Cobaltous perchlorate was prepared from
