“…The well miscibility of PCL and PLA can be attributed to good interaction PCL with PLA when TBC is added as compatibilizer. Xiao and Yang 25 and Wang et al 12 research showed the same results. The reason is that TBC cause transesterification reaction between PLA and PCL which decreased the dispersed phase size and improve the compatibility.…”

“…Transesterification reactions of polyesters are often associated with of the decrease in molecular weight and the broadening of molecular weight distribution which results in the decrease the apparent viscosity of PLA/PCL blends compared that of pure PLA and pure PCL. 12 …”

“…An improvement of the toughness of such brittle polymers can generally be achieved by blending a ductile secondary phase into the base polymer. PCL, a ductile biodegradable polymer, has been chosen as a blending partner for PLA, [10][11][12][13][14][15] and the fracture properties of PLA/PCL are found to be greater than those of pure PLA. However, it is also found that the immiscibility of PLA and PCL causes phase separation, and tends to lower the fracture properties.…”

Poly(lactic acid) (PLA) and poly(ε-caprolactone) (PCL) blends with various components for melt-blown nonwovens were prepared by a twin-screw extruder. Tributyl citrate (TBC) was added in order to improve the miscibility between PLA and PCL. The results showed that small circular particles of PCL were dispersed in PLA matrix uniformly. The addition of PCL had the heterogeneous nucleation effect on the crystallization of PLA and decreased thermal stability of PLA. The flow of pure PLA and blends approached to Newtonian liquid at a low shear rate and expressed more obvious viscoelasticity at a high shear rate.

“…Harada et al [3], highlighted as this kind of reactive mixing brings to the formation of high molecular weight, grafted and/or cross linked, co-polyester-urethanes (see the reaction scheme of figure 9). This is confirmed by the results above discussed, since it was found that the increase in the torque values, and hence in viscosity, is strictly related to the amount of LTI added, as it can be seen in the graph of figure 1b and table I .…”

Polycaprolactone (PCL) is one of the earliest, commercially available, synthetic polymers characterized by a large set of biodegradation and mechanical properties that can be finely controlled by regulating the local environmental driving forces (ie, microorganisms, enzymes, hydrolysis). Owing to their faster resorbability and long‐term degradation in the presence of water (up to 3 to 4 years), PCL has been widely investigated as a bioinspired material able to target selective cell response via controlled intracellular resorption pathways. In comparison with other aliphatic polyesters, the superior rheological and viscoelastic properties render PCL easy to manufacture and manipulate into a wide range of three‐dimensional platforms (ie, porous scaffold, micro‐ and nanocarriers, and implantable devices). In this article, we discuss the main relationships between polymer synthesis, physical/chemical properties, and processing conditions to optimize the fabrication of biodegradable devices made of PCL, putting particular focus on drug delivery, tissue engineering. and green chemistry applications.
