摘要
在自行开发的10升小试连续聚合实验装置上,通过合理调整聚合体系醋酸乙烯酯(VAc)用量、pH值、反应停留时间等因素,提高醋酸乙烯酯(VAc)在丙烯腈(AN)/醋酸乙烯酯(VAc)共聚物中的含量。纺丝试验表明,高醋产品纺丝过程顺利,无毛丝、断头现象。
The aqueous precipitation copolymerization of vinyl acetate was investigated in a pilot device based on industrial processes. The results show content of vinyl acetate in acrylonitrile fibers can be increased by control dosage of vinyl acetate,pH value,reaction time. The filature tests indicate process is all right.
