Thermostable naphthalate-containing copoly(amide-imide)s with inherent viscosity of 0.53-0.96 dL/g were synthesized by reacting diacid-terminated naphthalate monomers with various diisocyanate-terminated polyimide prepolymers. The polyimide prepolymers were prepared by using 4,4-diphenylmethane diis
A newly synthetic method has been developed for the preparation of block copoly(urethaneimide) (PUI). The copolymer was yielded from the direct reaction of the prepolyurethane terminated with isocyanate and the prepolyimide terminated with anhydride. The latter is prepared by reacting an excess amou
Two series of amorphous fluoro-poly(ether-imide) (6F-PEI) and one series of fluoro-coploy(ether-imide) (6F-CoPEI) polymers based on 2,2bis(3,4-dicarboxyphenyl) hexafluropropane dianhydride (6FDA) and di-ether-containing diamines: 1,2 -bis(4-aminophenoxy)benzene (o-BAPOB) and 4,4 -bis(4-aminophenoxy)
A new series of six-member sulfonated copolyimides (SPIs) were prepared by one-step solution copolycondensation from 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTDA), 1,2-dihydro-2-(4-amino-2-sulfophenyl)-4-[4-(4-amino-2-sulfonphenoxy)-phenyl] (2H)phthalazin-1-one (S-DHPZDA), 4,4bis(4-aminophen
## SYNOPSIS Copoly(ethy1ene terephthalate-imide)s (PETI) were prepared by melt polycondensation of bis(2-hydroxyethy1)terephthalate (BHET) and imide containing oligomer, i.e., 4,4'-bis[(4carbo-2-hydroxyethoxy)phthalimido]diphenylmethane (BHEI). The apparent rate of polycondensation reaction was fa
