合成了不同化学结构的聚醚酰亚胺 ( PEI)并用于 4 ,4′-二氨基二苯甲烷四缩水甘油醚 ( TGDDM)环氧树脂的增韧改性 ,以 DSC,TRLS和 SEM等方法研究了体系相分离过程中相容性和熔融粘度对相分离过程和结构的影响 ,对固化反应诱导相分离中相结构的控制提出初步的看法
Polyetherimide (PEI) with different chemical structure was synthesized and used for the toughening modification of 4, 4’-diaminodiphenylmethane tetraglycidyl ether (TGDDM) epoxy resin. DSC, TRLS and SEM The influence of compatibility and melt viscosity on the phase separation process and structure during the phase separation was studied. The preliminary observations on the control of the phase structure in the phase reaction induced by solidification reaction
