A process for producing a polymer includes polymerizing a monomer system containing a compound of formula: Ar—O—Ar—C(═O)—X—C(═O)—Ar—O—Ar in a reaction medium containing a Lewis acid. In the formula, X is an aliphatic moiety, and Ar is an aromatic moiety. The reaction medium further includes a dielectrophile. The dielectrophile is a compound of formula: L-(O═)C—Ar—C(═O)-L, in which L is a leaving group.
生产聚合物的工艺包括在含有路易斯酸的反应介质中聚合含有式化合物的单体体系: Ar-O-Ar-C(═O)-X-C(═O)-Ar-O-Ar 在含有路易斯酸的反应介质中聚合。 式中,X 是脂肪族分子,Ar 是芳香族分子。 反应介质还包括亲电剂。 亲电介质是一种式化合物: L-(O═)C-Ar-C(═O)-L,其中 L 是离去基团。
