摘要

<正>A novel cross-linking process using two high molecular weight aromatic poly（thioether）s

which were synthesized by the reactions of 4

4′-thiobisbenzenethiol with 4

4′-difluorobenzophenone and 4

4′-difluorodiphenylsulfone

respectively

and commercially available lower molecular weight poly（p-phenylene sulfide）was investigated.These reactions were carried out in bulk by the addition of silver tetrafluroborate andα

α′-dibromo-p-xylene at 190℃over a period of 45 min. Furthermore

the same procedure could be modified to cross-link compression-molded films of these three polymers.The thermal and solubility behaviors of these polymers before and after cross-linking reactions

are presented.
