在无水AlCl3及N 甲基吡咯烷酮 (NMP)存在下 ,以 4 ,4′ 二 (α 萘氧基 )二苯酮 (DNBP)作为第三单体 ,将其与 4 ,4′ 二苯氧基二苯酮 (DPBP)和对苯二甲酰氯 (TPC)在 1 ,2 二氯乙烷 (DCE)中进行低温溶液共缩聚反应 ,合成了一系列聚醚酮醚酮酮 含萘环聚醚酮醚酮酮无规共聚物 ,用IR、DSC、TG及WAXD等方法对其结构和性能进行了表征与测试。研究结果表明共聚物的玻璃化转变温度 (Tg)要比纯PEKEKK的高 ,而其熔融温度 (Tm)和结晶度 (XC)则随共聚物中含萘环PEKEKK结构单元含量的增加而逐渐降低。共聚物具有优异的耐热性能及抗腐蚀性能
In the presence of anhydrous AlCl3 and N-methylpyrrolidone (NMP), 4,4’-bis (α-naphthyloxy) benzophenone (DNBP) was used as the third monomer to react with 4,4’-diphenoxy A series of polyether ketone ether ketone ketones containing naphthalene ring polyether ketone were synthesized by copolycondensation of diphenyl ketone (DPBP) and terephthaloyl chloride (TPC) in 1, 2 dichloroethane (DCE) Ether ketone ketone random copolymer, its structure and properties were characterized and tested by IR, DSC, TG and WAXD methods. The results show that the glass transition temperature (Tg) of copolymer is higher than that of pure PEKEKK, while the melting temperature (Tm) and crystallinity (XC) of copolymer decrease with the content of PEKEKK containing naphthalene ring in the copolymer . Copolymer has excellent heat resistance and corrosion resistance
