| titleOfInvention |
Prepolymer and resin composition of modified composite bismaleimide resin, and prepreg and laminated board manufactured by using prepolymer and resin composition |
| abstract |
The invention discloses a prepolymer of modified composite bismaleimide resin, which is a prepolymer of composite bismaleimide resin and propenyl phenoxy compound, wherein the weight ratio of the composite bismaleimide resin is as follows: prepolymer of propenyl phenoxy compound 100: 50 to 120. The invention adopts bismaleimide structures with special structures and compounds the bismaleimide structures, and the structures have steric effect in the reaction, so that the reaction speed can be controlled, and the bismaleimide can be fully hot-melted and reacted with propenyl phenoxy compounds; thereby solving the problems of uncontrollable reaction and manufacturability of the modified bismaleimide resin in the prior art. |
