A novel soluble polyamide containing xanthene structure and trifluoromethylphenoxy pendent
摘要:
A novel polyamide containing xanthene structure and trifluoromethylphenoxy pendent was prepared from 9,9-bis[4-(4aminophenoxy)phenyl]xanthene,a novel diamine with 2-(4-trifluoromethylphenoxy)terephthaloyl chloride,by the low temperature polycondensation.This new polyamide with the inherent viscosity of 0.95 dL/g was amorphous and readily soluble in polar solvents such as DMAc,m-cresol,etc.This polyamide showed the glass transition temperature(Tg)of 236℃,decomposition temperature (Td)at 5% weight loss of 455℃ and char yield of 56% at 800℃ in N2.Transparent,flexible,and tough film of the polymer cast from DMAc solution exhibited tensile strength of 93 MPa,elongation at break of 14%,initial moduli of 2.2 GPa.The electric properties such as the dielectric constant of 3.03(1 MHz)and surface resistance(2.78×1014Ω),and the moisture uptake of 1.36% were also described.
