摘要

Abstract

Poly(

-arylene sulfide ketone/Schiff base) copolymers (PASK/SB) were prepared by solution polycondensation of 4

4′-diflurobenzophenone (DFBP) and

-phenyl(4

4′-diflurodiphenyl) ketimine (DFBI) with sodium sulfide in the presence of sodium hydroxide under normal pressure. Elemental analyses

FT-IR

NMR

DSC

TGA and XRD were used to characterize the resultant copolymers. It was found that the copolymers had good thermal properties with glass transition temperature (

) of 155.0-172.0℃

melting temperature (

) of 298-344℃

5% weight loss temperatures (

) of 471.0-501.5℃. These copolymers were almost amorphous with the content of DFBI beyond 30%. The polymer with 100% DFBI had excellent solubility

and it could dissolve in some solvents such as tetrahydrofuran (THF) and

-methyl-2-pyrrolidone (NMP). The processability of polymers was improved. Meantime the viscosity of PASK made from hydrolysis of PASK/SB (H-PASK/SB) was greatly improved from 0.135 dL/g to 0.605 dL/g.
