PACMO-b-PDPA两亲性嵌段聚合物的合成及其纳米自组装
Synthesis of amphiphilic block copolymer PACMO-b-PDPA and its self-assembly
摘要
Abstract
For the preparation of pH-responsive Poly (N-acryloylmorpholine) based nano-drug carriers, a series of am-phiphilic block copolymer poly(acryloyl morpholine)-b-poly(2-(diisopropylamino)ethyl methacrylate) (termed as PACMO-CTA and PACMO-b-PDPA) with different PDPA chain length were synthesized via two-step re-versible addition fragmentation chain transfer (RAFT) polymerization. The structure of the products were char-acterized by Fourier transform infrared spectrum(FT-IR), proton nuclear magnetic resonance (1H-NMR)spec-trometry , gel permeation chromatography(GPC). The results showed that the molecular weight of the polymers were controlled and the molecular weight distribution was narrow (Mw/Mn<1.2) in accordance with the funda-mental characteristics of RAFT active polymerization. Moreover, the nanoparticles formed by self-assembly were spherical and the average particle size were less than 200 nm, which meet the requirement of nano-drug carriers.关键词
