Dear Mohammadali Rezaei, if it is of a living type. Other thing to know is that successfull anionic polymerization requires extremely pure reagent and media, so even within the system itself there is no extra source to react with propagating chain ends sites. Termination by recommbination is also excluded by repulsion between same charges end groups My Regards

What type of anionic polymerisation are you doing?

Dear all, following an interesting chapter wretten by Prof. M. Szwarc on the modes of termination in anionic polymerization. My Regards
