Abstract
- The synthesis of novel branched/star copolymers which possess unique physical properties is highly desirable. Herein, a novel strategy was demonstrated to synthesize poly(&epsilon<br />caprolactone) (PCL) based miktoarm star (&mu<br />star) copolymers by combining ring-opening polymerization (ROP), styrenics-assisted atom transfer radical coupling (SA ATRC), and atom transfer radical polymerization (ATRP). From the analyses of gel permeation chromatography (GPC), proton nuclear magnetic resonance (1H NMR), and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), well-defined PCL-&mu<br />PSt (PSt: polystyrene), and PCL-&mu<br />PtBA (PtBA: poly(tert-butyl acrylate) &mu<br />star copolymers were successfully obtained. By using atomic force microscopy (AFM), interestingly, our preliminary examinations of the &mu<br />star copolymers showed a spherical structure with diameters of ca. 250 and 45 nm, respectively. We successfully employed combinations of synthetic techniques including ROP, SA ATRC, and ATRP with high effectiveness to synthesize PCL-based &mu<br />star copolymers.
