The triarm block copolymers comprising one poly-MMA arm and two poly-CL arms were synthesized by changing some polymerization conditions such as monomer/initiator concentration, polymerization time. The effect of the reactions conditions on the polydispersity and molecular weights was also investigated. The block lengths of the block copolymers were calculated by using H-1-nuclear magnetic resonance (H-1-NMR) spectrum. It was observed that the block length could be altered by varying the monomer and initiator concentrations. The characterization of the products was achieved by using H-1-NMR, Fourier-transform infrared spectroscopy, gel-permeation chromatography, differential scanning calorimetry, thermogravimetric analysis and fractional precipitation techniques.eninfo:eu-repo/semantics/closedAccessAtom Transfer Radical PolymerizationRing-Opening PolymerizationOne-Step PolymerizationTriarm Block CopolymerBlock LengthArticle736Q2Q214971513WOS:000376248900001
