原位聚合液晶环氧改性环氧树脂的研究

摘要

研究了原位聚合PHBHQ对环氧树脂的改性作用。结果表明，随着PHBHQ含量的增加，环氧树脂的冲击强度明显得到提高，而其他性能也有不同程度的改善，并采用SEM分析了PHBHQ/CYD128复合体系的微观结构。%The epoxy resin (CYD-128) modified by in-situ polymerized liquidcrystialline epoxy (PHBHQ) has been discussed. The results show that the epoxy resin impact s trength can be enhanced greatly with the content of PHBHQ increasing and other p roperties are enhanced to varying degrees too. The microstructure of PHBHQ/CYD -128 compound has been observed by SEM.
