Synthesis and structural characterization of novel chiral nanostructured poly(esterimide)s containing different natural amino acids and 4,4′-thiobis(2-tert-butyl-5-methylphenol) linkages

Abstract

Pyromellitic dianhydride (benzene-1,2,4,5-tetracarboxylic dianhydride) (1) was reacted with several amino acids in acetic acid and the resulting imide-acid [N,N′-(pyromellitoyl)-bis-L-amino acid diacid] (4a–4d) was obtained in high yield.

Novel Bioactive Chiral Poly(amide-imide)s Containing Different Amino Acids Linkages: Studies on Synthesis, Characterization and Biodegradability

Abstract

In this paper chiral bioactive poly(amide–imide)s (PAI)s were synthesized from four different diacids containing chiral amino acids with 4,4′-methylene bis(3-chloro 2,6-diethylaniline) as a diamine via direct polycondensation reaction in a system of tetra-

Preparation of sulfonated poly(ethylene terephthalate) nanofibrous membranes for removal of basic dyes

Abstract

In this investigation, a nanofibrous sulfonated poly(ethylene terephthalate) (SPET) membrane was prepared by electrospinning of the SPET solution in trifluoroaceticacid (TFA)/dichloromethane (DCM) mixture. The produced nanofibers had diameter ranging from 300 nm to 1 μm.
