TLDR
In this paper, the copolymerization of 2-methyl-2-oxazoline and N-phenyl maleimide in bulk or in solution, at 60°C or room temperature, is reported.Abstract:
The copolymerizations of 2-methyl-2-oxazoline and N-phenyl maleimide in bulk or in solution,at 60°C or room temperature are reported. The initiation is spontaneous and is due to the formation of zwitterion by interaction of the two monomers. The copolymers are statistical,more rich in maleimide units and propagation reaction can take place both by anions and zwitterions.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.
