Synthesis and Characterization of a Series of Star-Branched Poly(epsilon-caprolactone)s with Nanoscale Molecular Architectural Variation

Choi J., Song H.J., Kwak S-Y, Seoul National University, KR

In this study, a series of star-branched poly(epsilon-caprolactone)s (SPCLs) was synthesized with nanoscale molecular architectural variation in arm numbers and lengths by ring-opening polymerization under bulk condition. Arm numbers were varied to be 3, 4, [...]

Viscoelastic Relaxation and Molecular Mobility of Hyperbranched Poly(epsilon-caprolactone)s in Their Melt State

Song H.J., Choi J., Kwak S-Y, Seoul National University, KR

The dynamic viscoelastic relaxation behavior and the molecular mobility of hyperbranched poly(epsilon-caprolactone)s (HPCLs) possessing the molecular architectural variation and their linear counterpart, linear poly(epsilon-caprolactone) (LPCL), were characterized and evaluated in conjunction with their specific molecular [...]
