| Popis: | We present new polymeric amphiphiles derived from N-acryloyl derivatives of the cyclic secondary amines: morpholine, piperidine, and azocane polymerized by reversible addition−fragmentation transfer (RAFT) polymerization. Both homopolymerization and block copolymerization of N-acryloylmorpholine (AM), N-acryloylpiperidine (AP), and N-acryloylazocane (AH) were carried out. The block copolymeric amphiphiles, poly[(N-acryloylmorpholine)-block-(N-acryloylpiperidine)] (PAM-PAP) and poly[(N-acryloylmorpholine)-block-(N-acryloylazocane)] (PAM-PAH) were investigated, PAM being a hydrophile, and PAP and PAH being hydrophobes. Moreover, to compare PAM as a hydrophilic block with poly(ethylene glycol) (PEG), poly[(ethylene glycol)-block-(N-acryloylpiperidine)] (PEG-PAP) was also formed. In all cases, the degree of polymerization was well-controlled and polymers were obtained in monomodal distributions. The macroamphiphile aggregates in water were reproducibly well-formed by dialysis with a size range between 10 and... |
