With those in mind, this research aimed to characterize the physico-chemical properties of a series of PBS-DLS-PEG copolymers to investigate their suitability for melt and solution processing. By varying the segmental ratio and the concentration of the co-monomeric units, polymers of fine-tuned structure were synthesized and their chemical, physical and thermal properties were characterized. The processibility of PBS-DLS-PEG copolymers was thoroughly assessed specifically for 3D printing and electrospinning for future fabrication of multiscale structures. The polymer melt flow behavior and crystallization from the melt was examined to elucidate any changes which could cause shrinkage and binding between subsequent layers during 3D printing. Likewise, for electrospinning, the copolymer solution ability to form uniform and continuous nanofibers, their spinnability, and the control over fiber diameter were investigated as well.
