TLDR
In this paper, the authors describe alternating copolymerization in which two kinds of monomer interact with each other to generate zwitterion intermediates leading to the production of alternatingcopolymers.Abstract:
This chapter describes alternating copolymerizations in which two kinds of monomer interact with each other to generate zwitterion intermediates leading to the production of alternating copolymers. Since zwitterions are responsible for both initiation and propagation in these systems, it is not necessary to employ a catalyst (initiator) or high-energy irradiation to induce the copolymerization. Thus, this type of copolymerization is sometimes called “no-catalyst alternating copolymerization via zwitterion intermediates” or “spontaneous alternating copolymerization via zwitterion intermediates.” These alternating copolymerizations have been developed mainly by the present authors and co-workers in the past decade.(1)read more
