Orthogonal polymerization of aziridine with cyclic carbonates for constructing amphiphilic block copolymers

Abstract

Orthogonal polymerization of aziridine and cyclic carbonates is developed for constructing amphiphilic block copolymers, followed by acidification to construct polysomes.

Combining Cationic and Anionic Polymerizations using a Universal Mediator: Enabling Access to Two- and Three-Mechanism Block Copolymers

“…Polymer chemists can combine multiple mechanisms into a single polymer chain through a variety of strategies. Common methods -such as the coupling of two homopolymer chains, [5][6][7] end-group modification, [8][9][10][11][12][13][14][15][16][17][18][19][20][21] or the use of multifunctional initiators [22][23][24][25] -require additional synthetic steps and/or are limited in the architecture and number of blocks in the final material. The use of a universal mediator that can support multiple mechanisms without modification is an elegant solution to these challenges (Figure 1A).…”
