摘要: 6-氧化-6-氢-二苯基(c,e)(1,2)氧杂磷酰基-1,4-二羟基苯、对苯二甲酰氯(p-DC)、癸二酰氯(犛犅)通过溶液聚合合成含磷酰杂菲共聚酯。采用红外光谱、凝胶渗透色谱、差示扫描量热仪、热失重分析仪、热台偏光显微镜、广角x射线衍射等对聚酯的合成、聚集态结构、热性能等进行了研究。结果表明,可以通过调节共聚酯中SB与p-DC的配比改变其结晶性和玻璃化转变温度(Tg)。SB与p-DC的配比低于4∶6时,共聚酯具有明显的结晶性,且其结晶能保持至355℃。随着聚酯中p-DC含量的增加,共聚酯的Tg从30℃上升至172℃,600℃时共聚酯热降解的剩碳率从4.7%上升至49.3%。

Abstract: Phosphorus-containing copolycsters were synthesized via solution polycondensation from 2-}6-oxide-6H-dihenz( c,c)(1,2) oxaphos-phorin-6-yl〕-dihydroxyphenylene, schacoyl chloride, and p-dihen-zoyl chloride. The structures and thermal behaviors were investigated by FT-IR,GPC, DSC, TGA,POM, and WXRD. The properties of the copolycsters can he adjusted by changing the mol ratio of scha-coyl to p-dihcnzoyl.八、the ratio was lower than 4:6,the copolycster was crystalizahle with a melting point about 355℃.When the mol ratio changed from 10/0 to 1 /9,the Tg increased from 30℃to172℃,the char yield at 600℃increased from 4.7%to 49.3%.
