摘　　要：从有机硅改性(化学改性和物理共混)和合成新型含硅环氧树脂单体/低聚物两方面,综述了有机硅改性耐高温环氧树脂的研究进展,探讨了如何进一步提高环氧树脂的耐温等级、改善固化物脆性。最后对有机硅改性耐高温环氧树脂的发展趋势进行了展望。Siloxane modified epoxy was summarized in the two parts,i. e.,commercial epoxy resin modification（including chemical modification and physical blending）and novel siloxane modified epoxy oligomers synthesis. And how to improve the thermal stability further and enhance the ductility of the cured resin was discussed. Finally,the development trend of silicone modified epoxy resin was prospected.
