摘　　要：以4-氯邻苯二甲酸酐、多氯代苯、复合催化剂为原料,合成了聚酰亚胺单体。乙腈重结晶后水解、001×7强酸性阳离子交换树脂和D113阳离子交换树脂除去金属离子及乙酸酐脱水得电子级聚酰亚胺树脂单体。用气相色谱法检测了产品的纯度,以红外、核磁等确定了产品的纯度,以原子吸收法检测了金属离子的含量。The monomer of polyimide,was synthesized by using normal reagents,4-chlorophthalic anhydride,phenyl poly-chloride,composite catalyst etc. After recrystallization from acetonitrile hydrolysis,001 × 7 strongly acidic cation exchange resins and D113 cation exchange resins removed metal ions,dehydration reaction with acetic anhydride,get electronic grade the monomer of polyimide. FTIR and1 H NMR were used to determine the product. It adopts flame atom absorb to determine trace metal ions in the monomer of polyimide.
