1·The melt flow index of the blends was increased when the content of PEEK was decreased and melt temperature was increased.

结果表明：共混物的熔体流动指数随PEEK含量的降低和熔体温度的升高而增加；

2·The stable production of the specialty P240 for tubing with large diameter was realized under the condition of low melt flow index.

大口径管材专用树脂P240实现了低熔体流动指数下的平稳控制。
