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 7.8x10(15<bold>)cm when the BMI content was </bold>20wt%, which still showed good insulation performance. The dielectric property of modified BADCy copolymer remained the good stability from 0.1Hz to 1MHz. Compared to pure BADCy system, the breakdown property of BMI/BADCy blend reached the maximum value of 77.9kV/mm when the content of BMI was 20wt%, which was still about 1.22 times. The thermal property and thermal conductivity property of the copolymer were higher than BADCy system.
