A PES-PC (polyethersulfone-polycarbonate) multi block random copolymer was synthesized with two oligomers, polyethersulfone and polycarbonate. The effects of the copolymer, as a compatibilizer, on the morphology and...
A novel bifluoro-monomer containing naphthalene moieties was synthesized and characterized by using FTIR, MS and NMR. Different poly(aryl ether ketone)s based on 1,4-bis(4,4′-fluorobenzoyl) naphthalene were prepared ...
C1s and O1s of the 3,5-bitrifluoromethylated poly(aryl ether) terminated with phenylethynyl moieties(2CF3-PAE-PEP) before/after crosslinking were tested by the X-ray photoeletron spectroscopy(XPS). The measureme...
Block copolymers containing poly(aryl ether ketone) unit and different lengths of thermotropic liquid crystalline polyesters(TLCP) segments were synthesized by high temperature solution polymerization. The chemical st...

A new monomer, 1,4-bis(4-fluorobenzoyl) naphthalene(compound 2) was synthesized via a two-step reaction. 1,4-Naphthalenedicarboxylic acid chloride(compound 1) was prepared by using the acyl chlorization reaction of 1,...
The soluble poly(vinyl alcohol)-g-poly(ethylene glycol) monomethyl ether(PVA-g-MPEG) graft copolymer was prepared by two-step synthesis. The structure of the PVA-g-MPEG was characterized by 1H NMR. The phase change an...
