摘要
通过原位聚合与原位增容同步实施的方法制备PPO/PPO-g-PA6/PA6纳米共混物.在此基础上,对PPO介质中己内酰胺(CL)的聚合动力学的各种影响因素进行探讨.发现引发剂含量、小分子活化剂含量以及大分子活化剂活性点数目对聚合反应速度是有利于CL聚合的正效应,而PPO含量增加,使体系黏度增大,对CL聚合反应速度是不利于CL聚合的负效应.大分子活化剂的存在影响中后期的聚合反应速度.
A novel approach of in-situ-polymerization and in-situ-compatibilization is adopted to prepare PPO/ PA6 nanoblends. The effects of various parameters on kinetics of the anionic polymerization of CL in the presence of PPO are reported. It is found that the polymerization temperature, the amount of microactivator, initioator and the initiating sites on macroactivator contribute positively in the rate of polymerization, while the increase of PPO concentration acts negatively on the overall rate of polymerization due to diffusion and dilute effects The existing of macroactivator has negative effect on the rate of polymerization during late stage.
