Zwitterionic organocatalysis for ring-opening polymerization of cyclic esters Zwitterionic catalysis was powerful in simultaneously activating electrophile and nucleophile in organic transformations, however, its potential in polymerizations was untapped. Herein, a zwitterionic catalytic model for ring-opening polymerization (ROP) was introduced and a series quaternary ammonium carboxylate zwitterionic catalysts were designed and evaluated in ROPs of cyclic esters.

1. IntroductionAdolescence is an important stage in life. During this life stage, individuals tend to make first contact with information communication technologies (ICTs), with such use then becoming frequent.

This also encompasses different types of violence (1).
