Summary: Several solvents were utilized to investigate their influence on the formation of honeycomb patterns. The polymers PPO, PLGA and PLLGA were dissolved in different solvents or mixed solvents to form porous membranes. It was found that a good compatibility between the polymers and their solvents, and an appropriate volatility of the solvent were beneficial for the formation of regular structures. Moreover, C2HCl3 and CH2Cl2, neither of whose PPO solutions could form regular structures at 30 °C, were mixed at different volume ratios to dissolve PPO and fabricate porous structures. The result showed that a regular pattern was achieved when the volume ratio of C2HCl3:CH2Cl2 was 90:10 and that a special structure with big pores surrounded by small pores was obtained when the volume ratio of C2HCl3:CH2Cl2 was 10:90. Based on these phenomena, possible reasons were also proposed. magnified image

“…Poly(ether sulfone)s are normally considered as amorphous, in spite of their regular backbone, as they only crystallize, and to a limited extent, in the presence of solvents . However, Yokozawa and co‐workers have observed an increase in crystallinity for near‐monodisperse PES when comparing with normal engineering PES of similar average molecular weight.…”

The synthesis of telechelic poly(ether sulfone)s with methoxy end groups is reported. Molecular weights ranging from 1600 to 2800 g mol−1 and polydispersities of 1.1–1.2 are synthesized by chain‐growth condensation polymerization. The initiator is chosen by using semiempirical calculations and 19F NMR spectroscopy measurements. The polymers are characterized by NMR spectroscopy and matrix‐assisted laser desorption/ionization time of flight (MALDI‐TOF) mass spectrometry (MS), and are terminated by a methoxy group at one end and a fluorine at the other, and up to approximately 20% polymer of similar mass but slightly higher polydispersity, methoxy terminated at both ends, is present, along with less than 5% of polymer terminated at both ends by fluorine atoms. These do not need to be separated, and can be converted to methoxy‐ending telechelic blocks, yielding polyvalent, reactive rigid building blocks for copolymer synthesis.

“…However, dyeing of polyester fibers and fabrics with disperse dyes is a complex phenomenon and is often a challenge to the dyers, the main reasons for which are its high degree of crystallinity, its hydrophobic nature, the absence of dye sites, very low swelling, low diffusion of the dye molecules, high glass‐transition temperature, and the absence of chemically reactive groups in the polymer. Extensive research has been carried out on modifying polyesters by solvents 1–7. Solvent treatments did not have any adverse effect on the other textile properties of polyester.…”
