一种氯甲基化聚醚醚酮及其合成方法
摘要：
一种新的氯甲基化聚醚醚酮及其合成方法。该氯甲基化聚醚醚酮化学结构式为：式中：n＝50-1000，其分子量为10,000-200,000，氯甲基化程度x＝0.1-3.0。其合成方法是采用浓度为80-100％的硫酸代替传统的含氯烷烃作为溶剂和催化剂，氯甲基烷基醚为氯甲基化试剂，合成氯甲基化聚醚醚酮。并通过反应温度、反应时间以及硫酸浓度调节氯甲基化聚醚醚酮的氯甲基化程度。所制备的氯甲基化聚醚醚酮材料的分子量为10,000-200,000，常压空气中玻璃化温度为100-160℃，氯甲基化程度为0.1-3.0。本发明解决了聚醚醚酮溶解性差及其导致的难以氯甲基化改性的难题，成功合成了氯甲基化聚醚醚酮，反应条件温和、操作方便、环境污染小。
摘要（英）：

The invention discloses a novel chloromethylated polyetheretherketone (PEEK) and a synthetic method thereof. The chloromethylated PEEK is represented by the following formula, wherein, n represents an integer in the range of 50-1000, the molecular weight is 10000-200000, and the chloromethylation level x is 0.1-3.0. The synthetic method is characterized in that: sulfuric acids with the concentration of 80-100 % are used to replace traditional chloroalkane as the solvent and catalyst, chloromethyl alkylether is used as the reagent for chloromethylation to synthetize the chloromethylated PEEK; and the chloromethylation level of the chloromethylated PEEK is regulated through reaction temperature, reaction time and the concentration of sulfuric acids. The prepared chloromethylated PEEK material has the molecular weight of 10000-200000, the vitrification temperature in normal pressure air is 100-160 DEG C, and the chloromethylation level is 0.1-3.0. According to the invention, the difficulties of bad dissolvability of PEEK and difficult modification through chloromethylation caused by the bad dissolvability are solved, the chloromethylated PEEK is successfully synthetized, and the advantages of mild reaction conditions, convenient operation and little environmental pollution are achieved.
