摘要:采用丙烯基苯和烯丙基酚两种化合物改性双马来酰亚胺(BMI)树脂,所得的改性BMI树脂都具有良好的溶解性和耐高温性能。两者相比,烯丙基酚改性的BMI树脂力学性能优良,弯曲强度达128.0MPa;丙烯基苯化合物改性的BMI树脂的耐高温性更好,热分解温度达43O℃,在230℃时弯曲强度保留率达82.4%。
The bismaleimide was modified with alkenyl compounds (propenylbenzene/allylphenol compounds). The resins have good solubility in general solvents and excellent high temperature properties. Their Tg and degradation temperature are 290℃ and 302℃ ,430℃ and 409 ℃,respectively. And their flexural strength are 92.4 MPa and 128.0 MPa with high retention( 82.2% and 57.6%) at 230℃ , respectively.
