AbstractThis work investigates the thermal and rheological properties of the poly(L‐lactide‐co‐ε‐caprolactone), PLC, tapered block copolymer synthesized by ring‐opening polymerization (ROP) using stannous octoate (Sn[Oct]2) as an initiator. The PLC copolymer (LL: CL = 48.9:51.1 mol% from 1H‐NMR) was obtained as a transparent, elastomeric material with a tapered monomer sequencing (R = 0.38 from 13C‐NMR data) due to randomizing effect of transesterification. The Mn, Mw, and ĐM of the PLC copolymer from GPC are 8.04 × 104, 1.36 × 105, and 1.69 respectively. The obtained moduli of the copolymer at 100% and 300% strain are rather low at 0.91 and 1.16 MPa. The rheological properties of the PLC melt are studied in terms of steady and oscillatory shear flow. The master curves at a reference temperature of 150°C with 5% and 100% strain suggest that the copolymer melt may contain some regular microstructures, such as small crystalline domains of poly(L‐lactide), which remained intact at high strain deformation. The flow curve of the PLC melt at 150°C constructed from a cross model shows a Newtonian viscosity () of 6754 Pa‐s, a consistency index (k) of 0.59, and a Power Law index of 0.35 where the onset of Power Law behavior is observed at around 10 s−1. For the fabrication of the PLC nerve tubes, the best result is observed from the extruded PLC tubes with a combination of PEG porosifying agent leaching and phase immersion precipitation at 2°C using DMF/1,4‐dioxane (1:1) as a mixed solvent and ethanol/chloroform (9:1) as a non‐solvent. The porous tube obtained under this condition has a pore diameter and pore depth of approximately 2.3–2.5 and 30 μm respectively.
