“…It is generally required that a biodegradable polymer have certain attributes such as stability and durability to perform the intended functions, followed by breakdown and decomposition [5,6]. The degradation of biodegradable polymers often starts from the end-groups on the polymer backbone [7]. Since the degradation begins at the end, a high surface area is common to allow for easy access to chemical and biological species [8,9].…”

Polycaprolactone (PCL) fibers were produced using Forcespinning ® (FS). The effects of PCL concentration, solvent mixture, and the spinneret rotational speed on fiber formation were evaluated. The concentration of the polymer in the solvents was a critical determinant of the solution viscosity. Lower PCL concentrations resulted in low solution viscosities with a correspondingly low fiber production rate with many beads. Bead-free fibers with high production rate and uniform fiber diameter distribution were obtained from the optimum PCL concentration (i.e., 12.5 wt%) with tetrahydrofuran (THF) as the solvent. The addition of N, N-dimethylformamide (DMF) to the THF solvent promoted the gradual formation of beads, split fibers, and generally affected the distribution of fiber diameters. The crystallinity of PCL fibers was also affected by the processing conditions, spinning speed, and solvent mixture.

A pragmatic calcium‐based initiator for the synthesis of polycaprolactone copolymers

Abstract: Further understanding of the mechanism of the controlled ring‐opening polymerisation of ϵ‐caprolactone in the melt (70‐133 °C) using a simple calcium hydride‐based initiator has been made.
