An amino-terminated aliphatic hyperbranched polymer (HBP-NH 2 ) was used to modify ramie fabric. The molecular weight of HBP-NH 2 was established by GPC. HBP-NH 2 structure might represent as BA 4 BA 3 BA 3 (third generation). The total amine value, secondary amine value and primary amine value of HBP-NH 2 were...
A new amino-terminated hyperbranched polymer (at-HBP) was synthesized, and its salt-free dyeing property on ramie fabric was studied. The structure and molecular weight of at-HBP were established by Fourier transform infrared spectrometer, H nuclear magnetic resonance and gel permeation chromatography. The untreated ramie fabric and modified ramie fabrics were characterized by an X-ray diffraction...
Novel ester-containing gemini imidazolium surfactants were synthesized from various aliphatic acids (C 12 , C 14 , C 16 ), 1-methylimidazol, and 2,2-bis (bromomethyl)-1,3-propanediol with a two step reaction. The surfactants are abbreviated as [C n im] 2 (n=12, 14, 16). The chemical structures of the prepared compounds were confirmed by 1 H NMR, IR spectra,...
