前人曾报道聚丙烯腈(PAN)纤维在加压、或在酸碱作用下的水解研究。本文叙述了PAN废丝在ZnCl_2催化下的水解过程,和各种条件对PAN水解产物的粘度和组成的影响。扫描电镜实验发现,水解过程中
Previous reports on polyacrylonitrile (PAN) fibers under pressure, or acid-base hydrolysis studies. This paper describes the hydrolysis of PAN waste wire catalyzed by ZnCl 2 and the influence of various conditions on the viscosity and composition of the PAN hydrolyzate. Scanning electron microscopy experiments found that the hydrolysis process
