中文摘要:

(芳基醚酉同类) Poly, s (PAEK ) 成功地经由亲核的芳香的替换(SNAR ) 被综合机制,用离子的液体同样绿的反应媒介。包括单体集中,脱水时间,聚合温度和持续时间, IL 阳离子和阴离子自然的各种各样的反应参数的影响,在 PAEK 之上,分子的重量被调查。另外, IL 的结合氢的能力的怪癖被调查。2,2 二度(4-hydroxyphenyl ) 的相互作用有 IL 的丙烷(bisphenol A ) 在 PAEK 上有强烈影响合成。各种各样的中等分子的重量 PAEK 在高收益被获得了,分子的重量从 10000 ~ 18000 g mol1 。

英文摘要:

Poly(aryl ether ketone)s (PAEKs) were successfully synthesized via nucleophilic aromatic substitution (SNAR) mechanism, using ionic liquids as green reaction media. The influence of various reaction parameters including monomer concentration, dehydration time, polymerization temperature and duration, IL's cations and anions nature, upon PAEKs molecular weight was investigated. In addition, the peculiarities of hydrogen-bonding ability of ILs were investigated. The interaction of 2,2-bis(4-hydroxyphenyl) propane (bisphenol A) with ILs has a strong influence on PAEKs synthesis. Various moderate molecular weight PAEKs have been obtained in high yields with molecular weights ranging from 10000 to 18000 g mol-1.
