A method for the preparation of a poly(ether ether ketone) (PEEK) includes: preparing the PEEK by aromatic nucleophilic substitution in the presence of: a) particulate sodium carbonate (Na2CO3), wherein said particulate sodium carbonate has a particle size distribution as follows: D90≥45 μm and D90≤250 μm and D99.5≤710 μm, wherein said particle size distribution is measured by mechanical sieving in accordance with ASTM E 359-00 (reapproved 2005), wherein said measurement is based on the mechanical separation of various fractions on a series of superimposed sieves which are superimposed by descending order of opening mesh of 1000 μm, 500 μm, 250 μm, 180 μm, 125 μm, 90 μm, 63 μm, and 45 μm; and b) potassium carbonate (K2CO3) in an amount ranging from 0.001 to about 0.05 mol K/mol Na.
一种制备
聚醚醚酮(PEEK)的方法包括:在存在以下物质的情况下,通过芳香族亲核取代制备 PEEK: a) 颗粒
碳酸钠(Na2CO3),其中所述颗粒
碳酸钠的粒度分布如下:D90≥45 μm 和 D90≤250 μm 以及 D99.5≤710 μm,其中所述粒度分布是根据 ASTM E 359-00(2005 年重新批准)用机械筛分法测量的,所述测量是基于在一系列叠加筛上对各种馏分进行机械分离,这些叠加筛的开口目数由小到大依次为 1000 μm、500 μm、250 μm、180 μm、125 μm、90 μm、63 μm 和 45 μm;b)
碳酸钾(K2CO3),其用量范围为 0.001 至约 0.05 摩尔 K/摩尔 Na。
