PEN固相缩聚反应的实验研究

Experimental research on PEN solid phase polycondensation reaction

为了提高PEN的生产质量,需要从宏观的角度来研究各种因素上世纪对缩聚反应的影响.以经过预先结晶的PEN预聚体切片为原料,采用实验的方法,研究了反应温度对PEN固相缩聚反应的影响.

In order to improve the quality of PEN, should research the effects of all kinds of factors on polycondensation reaction from the macroscopical view. Taking PEN prepolymer slices which are crystallized in advance as raw material, adopting experimental method, researches the effect of reaction temperature on PEN solid phase polycondensation reaction.
