Synthesis of polysiloxane/polyamine block copolymer using uniform size poly(dimethylsiloxane) with reactive end-groups

Poly(dimethylsiloxane) (poly(DMS))/poly(N‐tert‐butylaziridine) (poly(TBA)) block copolymer was synthesized by two different techniques; (1) the coupling reaction of poly(DMS) having a dimethylaminopropyl end‐group (1) with living poly(TBA) (2) which was prepared with methyl trifluoromethanesulfonate...

Description
Summary:Poly(dimethylsiloxane) (poly(DMS))/poly(N‐tert‐butylaziridine) (poly(TBA)) block copolymer was synthesized by two different techniques; (1) the coupling reaction of poly(DMS) having a dimethylaminopropyl end‐group (1) with living poly(TBA) (2) which was prepared with methyl trifluoromethanesulfonate as an initiator, and (2) the polymerization of N‐tert‐butylaziridine (5) using poly(DMS) having a p‐toluenesulfonyl ester end‐group (4) as macromolecular initiator, respectively.
