摘 要: | 本文对PA6固相聚合(SSP)过程中影响聚合产物相对分子质量(RMW)的因素进行了研究.结果表明:RMW随RMW调节剂用量增加稍微增加后再迅速减小;聚合时间增加,则PA6的RMW开始迅速增加,随后逐渐减慢.

THE STUDY OF THE INFLUENCE FACTORS OF SOLID-STATE POLYMERIZATION ON RELATIVE MOLECULAR WEIGHT IN NYLON 6 |

Abstract: | The influence factors of solid-state polymerization(SSP) on relative molecular weight(RMW) in nylon 6 are studied. The results show that RMWs decrease with increasing of the content of RMW regulator, and that RMWs increase with in-creasing SSP times, and that RMWs for the viscosity method and end - group method agree basically, but the values of the former are a little higher than the values of the latter. |
