Preparation and characterization of a novel fluorescent hyperbranched poly(phenylene oxide);

Investigation of hyperbranched PPS/PPS composite fiber shows that proper amount of hyperbranched PPS can increase the crystallinity of linear PPS;therefore tensile strength increases.

Non-isothermal crystallization kinetics of hyperbranched PPS/PPS blend fiber was studied by differential scanning calorimetry (DSC).

A novel hyperbranched PEU(PHEU) was synthesized by mixing hyperbranched polyether(PHEMO) with hexaethylene diisocyanate(HDI) in the electrolyte.

A series of aliphatic hyperbranched polyethers were synthesized by using the trimethylol propane as core molecule,and their molecular structures were characterized by IR,hydroxyl value.

A novel kind of polymer electrolyte based on hyperbranched polyether was prepared,and its ionic conductivity was studied by electrochemical impedance spectroscopy(EIS).

Hydroxyl-terminated(HPEEK-OH) and fluoro-terminated(HPEEK-F) hyperbranched poly(ether ether ketone) were prepared from the mixture of hydroquinone(A_2) and 1,3,5-tris[4-(4-fluorobenzoyl)phenoxy]benzene(B_3) with different A_2/B_3 mass ratios.

Fluorin-terminated hyperbranched poly(ether ether ketone)(HPDEEK-F) was synthesized via A 2+B 3 reaction.

Hyperbranched poly(aryl ether ketone)s(HPETFDEK-F) were synthesized from the combination of 3,3′,5,5′,-tetramethyl biphenyl-4,4′-diol(A_2) and B_3,a novel monomer 1,3,5-tris[4-(4-flourobenzoyl)phenoxy] benzene synthesized in our lab.
