Abstract
|
|
|
|
In this study, polysilanes were synthesized by electroreduction with different monomers such as CH3HSiCl2, PhSiCl3, CH3SiCl3 and (CH3)2SiCl2 by Mg electrodes under ultrasonic radiation. The effects of monomers and additives (p-dibromobenzene (DBB), naphthalene (NAPH) and anthracene (ANTH)) on the reaction rate were investigated. Polymerization of PhSiCl3 among the four monomers showed the highest rate. pdibromobenzene (DBB) was proved the most effective additive. Based on the observations, some possible reaction mechanisms of the polymerization were proposed.
