摘　　要：The blend was synthesised with bismaleimide(BMI)resin and bisphenol A-based cyanate ester(BADCy)resin.The BMI/BADCy copolymer showed excellent dielectric and thermal conductivity properties.The volume resistivity of the copolymer was a little lower than BADCy system.The volume resistivity of blend was 7.8×10^(15)Ω·cm when the BMI content was 20 wt%,which still showed good insulation performance.The dielectric property of modified BADCy copolymer remained the good stability from 0.1 Hz to 1 MHz.Compared to pure BADCy system,the breakdown property of BMI/BADCy blend reached the maximum value of 77.9 kV/mm when the content of BMI was 20 wt%,which was still about 1.22 times.The thermal property and thermal conductivity property of the copolymer were higher than BADCy system.
