TLDR
In this paper, alternating copolymerization of 2-acryloxypropionic acid (APA) as a new MN with two MN monomers of phosphorus containing ethylene phenyl phosphonite (EPO) and ethylene Phenyl phosphite (EPI) have been disclosed.Abstract:
Alternating copolymerization of 2-acryloxypropionic acid (APA) as a new MN with two MN monomers of phosphorus containing ethylene phenyl phosphonite (EPO) and ethylene phenyl phosphite (EPI) have been disclosed. Copolymerizations took place without added catalyst to produce 1∶1 alternating copolymers of APA-EPO and of APA-EPI. The structures of the copolymers were determined by IR and NMR spectroscopy, elemental analyses, as well as the identification of the alkaline hydrolysis products. The copolymerizations were explained in terms of a mechanism of zwitterion intermediates involving a hydrogen transfer process.read more

Spontaneous Alternating Copolymerization via Zwitterion Intermediates
TL;DR: In this article, a nucleophilic monomer (MN) combines with an electrophilic one (ME) to generate a zwitterion [+]MN-M, which is responsible for the initiation and propagation of copolymerization.

No catalyst alternating copolymerization of cyclic imino ethers
Takeo Saegusa,Shiro Kobayashi +1 more
TL;DR: In this article, the general concept of no catalyst alternating copolymerization was introduced, in which a nucleophilic monomer M N is combined with an electrophilic one M E preferably in aprotic polar solvents to produce a zwitterion + M N −M E -, the key intermediate of the copolymers.
