Degradable poly(ester-ether urethane)s derived of AB2 miktoarm star copolymer poly(ethylene glycol-(ε-caprolactone)2) diol: Synthesis, characterization and degradation
چکیده انگلیسی

Four different miktoarm star copolymers poly(ethylene glycol-(ε-caprolactone)2) diol [PEG-PCL2] were obtained using α-diol-ω-methoxy poly(ethylene glycol) [MPEG-(OH)2] as macroinitiator/chain transfer agent in the ring opening polymerization (ROP) of ε-caprolactone (CL) catalyzed by tin(II) 2-ethylhexanoate [Sn(Oct)2]. PEG-PCL2 and 1,6-hexamethylene diisocyanate (HDI) were used as precursors of a new family of poly(ester-ether urethane)s PEUs. PEUs films were characterized by FT-IR, DSC, mechanical properties, water absorption, hydrolytic degradation and SEM.
