Electroinitiated chain polymerisation

Toppare [84] and Ito [85] have studied the effect of ultrasound on electroinitiated chain polymerisation. Although more detailed discussion is reserved for Chapter 6, for the sake of completeness brief mention will be made here. 

In this section we will focus on electroreductive and electrooxidative synthesis and touch briefly on the electrosynthesis of selected organometallics and electroinitiated chain polymerisation, previously introduced in Chapter 5. 

There are two techniques employed to investigate electroinitiated chain polymerisation. They are potentiostatic control (constant potential) and the more usual galvano-static control (constant current). 

Conducting polymers are quite different systems to the electroinitiated chain polymerisations discussed above being formed by a step-growth mechanism involving stoichiometric transfer of electrons. 

In 1970, Funt and Blain published a thorough study of the electroinitiated polymerisation of styrene in the presence of tetrabutylammonium perchlorate. The kinetics of these reactions were followed in methylene chloride with a cell provided with a sintered-glass membrane and a sampling device at the anode compartment. S-shaped time-conversion curves were obtained indicating the accumulation of chain carriers during the electrolysis. The results were treated assuming that the concentration of active species was directly proportional to the time-integrated current flow, and that no termination oc-...
